 Who's got two thumbs and a Secret Service-approved phone to tweet from? 
 
 On arriving in Washington on Thursday ahead of his inauguration, Donald Trump handed in his Android device in exchange for an unidentified locked-down phone, according to the Associated Press. 
 
 The phone comes with a new number that is known only to a limited number of people. This marks a big change for Trump, who's frequently on the line with friends, business contacts, reporters, foreign leaders and politicians. 
 
 Larry Johnson, who worked at the Secret Service from 1982 to 2006, said a smartphone given to a president would have extremely limited uses. "It's not really good for much," he said. 
 
 It's possible Trump's Twitter account would be operated from another phone, said Johnson, who now works as an executive at cybersecurity company CyberSponse. 
 
 But that's not where the phone's limitations would end. "You can't make a phone call, because it's too easy to be intercepted," Johnson said. "I can scare you with how easy it is." 
 
 The Secret Service declined to comment for this story.

 Barack Obama was the first president to use a mobile device approved by security agencies because of hacking concerns. Initially he had a heavily modified BlackBerry and later switched to another phone that had most features disabled. He was not known to use it for making or receiving calls, but it was one of few devices that had access to the @POTUS Twitter account. 
 
 Trump said earlier this week that he will keep using his existing Twitter account to communicate on social media, in addition the the @POTUS account.

 What does a Trump presidency mean for tech? Some say it might not be as bad you think. Others say his potential influence on the industry is "alarming." 
 
 Life, disrupted: In Europe, millions of refugees are still searching for a safe place to settle. Tech should be part of the solution. But is it? CNET investigates. ||||| WASHINGTON (AP) — A few hours after President-elect Donald Trump was briefed by intelligence officials about Russian meddling in the election, an Associated Press reporter called his cellphone seeking an interview. 
 
 The call went to voicemail and the reporter did not leave a message. About an hour later, Trump called back. 
 
 It's hard to imagine many politicians — particularly one about to become president of the United States — calling back an unknown number on their cellphone. 
 
 With Trump, it's simply how business gets done, whether he's fielding calls from real estate partners and longtime friends or foreign leaders and congressional lawmakers in the weeks after the election. 
 
 But as Trump prepares to take the oath of office Friday, the future of his ever-present Android smartphone is now a matter of national security. On Thursday, he told a friend that he had given up his phone, as security agencies had urged him to do. It was unclear whether he was following the lead of President Barack Obama, the nation's first cellphone-toting president, who exchanged his personal device for a Blackberry heavily modified for security purposes. 
 
 The friend who spoke with Trump spoke to The Associated Press on the condition of anonymity in order to disclose the private conversation. 
 
 The presidency has long been a lonely, isolating office, with security concerns keeping the commander in chief at a distance from the public. Under Obama, worries about cyber intrusions — particularly by foreign governments — pulled the president's technology deeper into the security bubble as well. Many of the functions on Obama's Blackberry were blocked and only a handful of people had his phone number or email address. 
 
 Trump doesn't email, but he uses his phone to tweet — something he's made clear he plans to continue in office. He's known to make calls early in the morning and late at night, often seeking input from multiple sources when making a decision. Sometimes he leaves a voicemail. 
 
 Christopher Ruddy, the CEO of Newsmax and a friend of the president-elect, described Trump's phone etiquette, as "just like one of his speeches, it's very stream of consciousness." 
 
 Sen. Bob Corker, R-Tenn., called Trump "amazingly accessible," saying the president-elect picks up his phone even when he doesn't know who is calling. 
 
 "My phone says, No Caller ID, so I'm not saying that it has anything to do with me," Corker said. "Nobody knows who it is that's calling when I'm calling." 
 
 Foreign leaders and diplomats took advantage of Trump's accessibility in the days after his election as they scrambled to find ways to reach him. Some called into Trump Tower hoping to be transferred to the president-elect's office. Australian Prime Minister Malcolm Turnbull got Trump's cellphone number from the golfer Greg Norman. 
 
 Trump's accessibility can create headaches for his aides, who can't always control who he's speaking to or what he's saying. After actress Meryl Streep blasted Trump during a Golden Globes speech earlier this month, a New York Times reporter called the president-elect at midnight to get a response. Trump's criticism of Streep dominated the news the following day, overshadowing his team's planned agenda. 
 
 For Obama, getting to use a Blackberry in office was considered a victory. He later switched to an iPhone that allowed him to send and receive email from a limited group of people, surf websites and read the news. 
 
 But Obama wasn't known to use his cellphone to make or receive telephone calls, according to individuals familiar with his technology use. Even senior government officials didn't have the number and instead reached the president through the White House switchboard. 
 
 The president also used the switchboard to place his calls, said the individuals, who weren't authorized to speak publicly and requested anonymity. 
 
 Obama had a phone in his control that he used to tweet, one of the only devices with access to the official presidential Twitter feed due to hacking concerns. But Obama rarely hit "send" on a tweet himself, and never without coordinating it with his staff, the individuals said. 
 
 If Trump does get rid of his cellphone, it could end up with a home not far from the White House. 
 
 Curators at the Newseum, which chronicles the First Amendment and the evolution of electronic communication, reached out to Trump's campaign in November about the prospect of acquiring his Android phone. They haven't heard back, said Carrie Christoffersen, the museum's curator of collections.

 A Clinton Foundation laptop and a thumb drive used to archive Hillary Clinton’s emails from her time as secretary of state are missing, according to FBI notes released on Friday. 
 
 Clinton emails recovered by FBI to be released just before election day Read more 
 
 The phrase “Clinton could not recall” litters the summary of the FBI’s investigation, which concluded in July that she should not face charges. Amid fierce Republican criticism of the Democratic presidential candidate, the party’s nominee, Donald Trump released a statement which said “Hillary Clinton’s answers to the FBI about her private email server defy belief” and added that he did not “understand how she was able to get away from prosecution”. 
 
 The FBI documents describe how Monica Hanley, a former Clinton aide, received assistance in spring 2013 from Justin Cooper, a former aide to Bill Clinton, in creating an archive of Hillary Clinton’s emails. Cooper provided Hanley with an Apple MacBook laptop from the Clinton Foundation – the family organisation currently embroiled in controversy – and talked her through the process of transferring emails from Clinton’s private server to the laptop and a thumb drive. 
 
 
 
 “Hanley completed this task from her personal residence,” the notes record. The devices were intended to be stored at Clinton’s homes in New York and Washington. However, Hanley “forgot” to provide the archive laptop and thumb drive to Clinton’s staff. 
 
 In early 2014, Hanley located the laptop at her home and tried to transfer the email archive to an IT company, apparently without success. It appears the emails were then transferred to an unnamed person’s personal Gmail account and there were problems around Apple software not being compatible with that of Microsoft. 
 
 The unnamed person “told the FBI that, after the transfer was complete, he deleted the emails from the archive laptop but did not wipe the laptop. The laptop was then put in the mail, only to go missing. [Redacted] told the FBI that she never received the laptop from [redacted]; however, she advised that Clinton’s staff was moving offices at the time, and it would have been easy for the package to get lost during the transition period. 
 
 “Neither Hanley nor [redacted] could identify the current whereabouts of the archive laptop or thumb drive containing the archive, and the FBI does not have either item in its possession.” 
 
 
 
 Clinton’s use of a private email server while in office has dogged her presidential campaign. The FBI has been criticised by Democrats for taking the rare step of publishing its account of confidential interviews with Clinton and others from the recently closed investigation, which found her to have been “extremely careless” in her handling of classified information. Hopes that this would draw a line under the issue, however, appear to have been dashed. 
 
 The FBI identified a total of 13 mobile devices associated with Clinton’s two known phone numbers that potentially were used to send emails using clintonemail.com addresses. 
 
 The 58 pages of notes released on Friday, several of which were redacted, also related that Hanley often purchased replacement BlackBerry devices for Clinton during Clinton’s time at the state department. Hanley recalled buying most of them at AT&T stores in the Washington area. Cooper was usually responsible for setting them up and synching them to the server. 
 
 Clinton’s closest aide, Huma Abedin, and Hanley “indicated the whereabouts of Clinton’s devices would frequently become unknown once she transitioned to a new device”, the documents state. “Cooper did recall two instances where he destroyed Clinton’s old mobile devices by breaking them in half or hitting them with a hammer.” 
 
 The notes also contain a string of admissions by Clinton about points she did not know or could not recall: “When asked about the email chain containing ‘(C)’ portion markings that state determined to currently contain CONFIDENTIAL information, Clinton stated that she did not know what the ‘(C)’ meant at the beginning of the paragraphs and speculated it was referencing paragraphs marked in alphabetical order.” 
 
 Armando (@armandodkos) FBI report confirms the only emails marked classified at the time Clinton received them were the 3 improperly marked "C" documents. p. 21 
 
 Clinton said she did not pay attention to the difference between top secret, secret and confidential but “took all classified information seriously”. She did not recall receiving any emails she thought should not have been on an unclassified system. She also stated she received no particular guidance as to how she should use the president’s email address. 
 
 In addition, the notes say: “Clinton could not recall when she first received her security clearance and if she carried it with her to state via reciprocity from her time in the Senate. Clinton could not recall any briefing or training by state related to the retention of federal records or handling of classified information.” 
 
 Clinton was aware she was an original classification authority at the state department, but again “could not recall how often she used this authority or any training or guidance provided by state. Clinton could not give an example of how classification of a document was determined.” 
 
 Nor could she recall any specific briefing on how to handle information associated with special access programme information. 
 
 “Clinton could not recall a specific process for nominating a target for a drone strike,” the notes say. 
 
 According to the notes, on 23 January 2009 Clinton emailed her predecessor, Colin Powell, to ask about his use of a BlackBerry. In his response, Powell told Clinton that if it became “public” that she was using a BlackBerry to “do business”, the emails could become “official records[s] and subject to the law”. 
 
 
 
 Powell wrote: “Be very careful. I got around it all by not saying much and not using systems that captured the data.” 
 
 Clinton told the FBI she understood Powell’s comments to mean that any of her work-related communications would be records of the government and “did not factor” the comments “into her decision to use a personal email account”, the documents say. 
 
 The release also includes technical details about how the server in the basement of Clinton’s home in Chappaqua, New York, was set up. 
 
 Clinton’s critics seized on the latest revelations. Trump’s full statement read: “Hillary Clinton’s answers to the FBI about her private email server defy belief. I was absolutely shocked to see that her answers to the FBI stood in direct contradiction to what she told the American people. After reading these documents, I really don’t understand how she was able to get away from prosecution.” 
 
 Jason Miller, senior communications adviser to Trump, said: “Hillary Clinton is applying for a job that begins each day with a top secret intelligence briefing, and the notes from her FBI interview reinforce her tremendously bad judgment and dishonesty. 
 
 
 
 “Clinton’s secret email server was an end run around government transparency laws that wound up jeopardizing our national security and sensitive diplomatic efforts.”

 He added: “Clinton’s reckless conduct and dishonest attempts to avoid accountability show she cannot be trusted with the presidency and its chief obligation as commander-in-chief of the US armed forces.” 
 
 The House speaker, Paul Ryan, said: “These documents demonstrate Hillary Clinton’s reckless and downright dangerous handling of classified information during her tenure as secretary of state. They also cast further doubt on the justice department’s decision to avoid prosecuting what is a clear violation of the law. This is exactly why I have called for her to be denied access to classified information.” 
 
 Reince Priebus, chair of the Republican National Committee, said: “The FBI’s summary of their interview with Hillary Clinton is a devastating indictment of her judgment, honesty and basic competency. Clinton’s answers either show she is completely incompetent or blatantly lied to the FBI or the public. 
 
 “Either way it’s clear that, through her own actions, she has disqualified herself from the presidency.” 
 
 The Clinton campaign insisted that it was pleased the notes had been made public. Spokesman Brian Fallon said: “While her use of a single email account was clearly a mistake and she has taken responsibility for it, these materials make clear why the justice department believed there was no basis to move forward with this case.”
– Well, it appears the Secret Service has pried Donald Trump's beloved Android phone from his tweeting fingers. An unidentified friend of Trump's tells the AP the new president handed over his phone Thursday on the advice of security advisers. The New York Times reports Trump's Android was replaced by an encrypted device that received Secret Service approval. Barack Obama, the first president to use a mobile device in office, started with a "heavily modified" Blackberry before moving to a mostly disabled iPhone. The devices were used to check email and news sites but rarely—if ever—for phone calls. This is all likely to cramp Trump's style. A Republican senator says the president was known for answering his phone even if he didn't recognize the number. He would even call back strange numbers that didn't leave a message. A former Secret Service agent tells Cnet Trump is unlikely to be able to use his new device for phone calls because they are way too easy to intercept. Trump's aides—some of whom are excited journalists and others won't have direct access to him—say he's likely to instead go office to office in person to get his "gossip" fix. It's possible he'll still be able to tweet. The Newseum in Washington DC has asked Trump about getting his Android to put on display.
