The National Security Agency's (NSA) continued surveillance of Israeli Prime Minister Benjamin Netanyahu and Israeli leaders may also have swept up private conversations involving members of Congress, the Wall Street Journal reported Tuesday night. 
 
 Although President Obama had promised to curb eavesdropping on world leaders who are U.S. allies after Edward Snowden leaked documents revealing the extent of the surveillance, there were a few leaders the White House wished to continue monitoring, including Netanyahu. 
 
 The original reason for the stepped up surveillance of Netanyahu, according to the WSJ, was the fear that he would "strike Iran without warning." By 2013, that fear had dissipated. The administration then became concerned about the Iran nuclear deal that was being negotiated. U.S. officials believed that the Israelis were spying on the negotiations and would try to scuttle the deal, the report said. 
 
 Further, the Journal reports that intercepted conversations between Israeli leaders confirmed Israel's knowledge of the talks, as well as its intent to undermine any nuclear deal with Iran by leaking its details. When Netanyahu and his top aides came to Washington to talk with Jewish-American groups and members of Congress to lobby against the deal, the NSA was there to pick up the conversations. 
 
 Senior officials told the WSJ that those conversations collected by the NSA raised fears "that the executive branch would be accused of spying on Congress." The White House wanted the information anyway, however, because it "believed the intercepted information could be valuable to counter Mr. Netanyahu's campaign." 
 
 So in order to avoid leaving a trail, the White House left it to the NSA to figure out what to share, and the NSA obliged, deleting names of members and any personal attacks on the administration. 
 
 National Security Council Spokesman Ned Price wouldn't comment on the intelligence activities written about in the Wall Street Journal's story, but he said in a statement, "[W]e do not conduct any foreign intelligence surveillance activities unless there is a specific and validated national security purpose. This applies to ordinary citizens and world leaders alike." 
 
 He added that the U.S. commitment to Israel's security is "sacrosanct" and "backed by concrete actions that demonstrate the depth of U.S. support for Israel." 
 
 The office of Speaker of the House Paul Ryan said only that it was looking into the matter. 
 
 Rep. Devin Nunes, chairman of the House Select Committee on Intelligence, said the committee would also be looking into the report. 
 
 "The Committee has requested additional information from the [Intelligence Community] to determine which, if any, of these allegations are true, and whether the IC followed all applicable laws, rules, and procedures," Nunes said in a statement Wednesday. 
 
 Before a campaign event in Cisco, Texas, Sen. Ted Cruz said he wasn't surprised that the administration was trying to intercept Netanyahu's communications, or even that conversations including members of Congress may have been swept up by the NSA, "because this administration views Congress, Republicans and sometimes even Democratic members of Congress as their enemy....At times, it seems like they view the American people as their enemy." 
 
 The allegations "are total nonsense," a spokesman for the Embassy of Israel in Washington told the WSJ. 
 
 Before Netanyahu came to address Congress, the NSA had intercepted Israeli messages that said Netanyahu wanted the "the latest U.S. positions in the Iran talks," the Journal wrote, signaling to to the administration that Netanyahu intended to use his address to reveal sensitive details about the negotiations. Secretary of State John Kerry then said as much to reporters on the eve of the speech. 
 
 Kerry justified his accusation by pointing to Israeli media reports, but those reports were a convenient source, given that "Intelligence officials said the media reports allowed the U.S. to put Mr. Netanyahu on notice without revealing they already knew his thinking. The prime minister mentioned no secrets during his speech to Congress," wrote the Journal.

 The US National Security Agency was forced on Sunday to deny that its director ever discussed a surveillance operation against the German chancellor with President Barack Obama, as the White House tried to contain a full-scale diplomatic crisis over espionage directed at allied countries. 
 
 The Obama administration appeared in disarray as it struggled with the fallout over the disclosure that the National Security Agency monitored the phone conversations of at least 35 world leaders, and that the phone of the German chancellor, Angela Merkel, had been monitored. 
 
 Early on Sunday, the White House refused to comment on an overnight report in the German tabloid Bild, which alleged that Obama was personally briefed about by the operation to target Merkel's phone by the NSA's director, Keith Alexander, and allowed it to continue. 
 
 That appeared to conflict with a second report, in the German newspaper Frankfurter Allgemeine Sonntagszeitung. It said that when Obama spoke to Merkel over the phone on Wednesday, he assured the German leader he had not previously known her phone had been monitored. 
 
 Caitlin Hayden, the White House's national security council spokeswoman, declined to comment on the reports, telling the Guardian: "We are not going to comment publicly on every specific alleged intelligence activity." 
 
 However just over three hours later, that position appeared to have been reversed, when the NSA said in a statement that Alexander "did not discuss with President Obama in 2010 an alleged foreign intelligence operation involving German Chancellor Merkel, nor has he ever discussed alleged operations involving Chancellor Merkel. News reports claiming otherwise are not true". 
 
 Bild cited "a secret intelligence employee who is familiar with the NSA operation against Merkel" in its story, which was widely-picked up by global media. 
 
 The intervention by the NSA was unusual – the agency rarely comments publicly on specific allegations about its surveillance activities. 
 
 However the White House and NSA are coming under intense pressure to reveal the extent to which Obama and senior administration officials knew about US surveillance operations targeting the leaders of allied countries. 
 
 The agency did not dispute another report in Germany, based on documents disclosed by the whistleblower Edward Snowden, that the NSA's Special Collection Service (SCS) had listed Merkel's phone number since 2002. The report, in Der Spiegel, said the phone number was still on the list – marked as "GE Chancellor Merkel" – weeks before Obama visited Berlin in June, raising the possibility that the German leader had been under surveillance for more than a decade. 
 
 In an SCS document cited by the magazine, the agency said it had a "not legally registered spying branch" in the US embassy in Berlin, the exposure of which would lead to "grave damage for the relations of the United States to another government". 
 
 A delegation of German intelligence officials are due to arrive in the US to meet counterparts in the coming days. They are expected to demand clarity on the nature and scope of NSA activities in their country. 
 
 'A greater focus'

 However in Washington, the first signs are emerging that Obama's administration may seek to distance itself from the NSA, concluding that the spy-agency has strayed beyond its remit and overreached. Many senior figures in Congress have already said the NSA failed to properly inform them of the nature and scope of its surveillance activities. 
 
 Lisa Monaco, a homeland security advisor to the White House, called on Friday for a "greater focus" to ensure the US was balancing "security needs with the privacy concerns all people share". Her op-ed piece in USA Today was widely interpreted as a signal of growing concern within the administration. 
 
 Monaco wrote: "We want to ensure we are collecting information because we need it and not just because we can." 
 
 In August, announcing a review of US intelligence activities in the aftermath of the first disclosures based on documents leaked by whistleblower Edward Snowden, Obama gave the impression that the NSA was solely focused on counter-terrorism measures. 
 
 "I don't have an interest and the people at the NSA don't have an interest in doing anything other than making sure that where we can prevent a terrorist attack, where we can get information ahead of time, that we're able to carry out that critical task," he said. "We do not have an interest in doing anything other than that." 
 
 The Spiegel report said the NSA's Berlin-based surveillance hub, adjacent to the Brandenburg gate, was one of several in Europe, citing a 2010 document that referred to branches existing in about 80 locations across the world, including Paris, Madrid, Rome, Prague, Geneva and Frankfurt. The article said it was not clear whether the monitoring of Merkel's phone included actual telephone conversations or was restricted to call data, but raised the question over whether a surveillance operation, which began three years before she became chancellor, was initially intended to gather intelligence ahead of the Iraq War, which Germany opposed. 
 
 Merkel, then in opposition, was critical of Germany's anti-war stance. Bild reported that the then-chancellor, Gerhard Schröder, was also the target of surveillance, at the behest of the George Bush administration. 
 
 A new dimension

 Revelations about the NSA monitoring foreign leaders – particularly allies – have blown open a dimension of the NSA scandal which, until now, has proven relatively uncontroversial in the US: surveillance conducted abroad. 
 
 The US debate over NSA surveillance has focused almost exclusively on operations that may involve US citizens – such as a program to collect the phone records of millions of Americans. Until the recent revelations, there was virtually no concern raised over surveillance involving foreign citizens, even among vocal critics of the NSA on Capitol Hill. 
 
 Legislation to reform the NSA, which is being introduced in both houses of Congress this week, focuses almost entirely upon surveillance activities that might involve US citizens. Few in Washington are challenging the administration's claim that "all nations" engage in similar forms of espionage. 
 
 However diplomatic sources have told the Guardian that the White House's declarations that its practices do not differ from those employed by "all nations" are deeply misleading. 
 
 The sources said that while the US, Russia, China, Britain and France are well-known to engage in aggressive cyber espionage, including against allies, many other countries do not have anywhere near the same surveillance infrastructure – and concentrate their more limited resources on counter-terrorism and serious crime. 
 
 The revelations about NSA activity in Germany were discussed on the US Sunday morning political talkshows. Speaking on Face the Nation, on CBS, the Republican Darrell Issa, the chairman of the House oversight and government reform committee was asked if he thought Obama had known about the surveillance of Merkel's phone. 
 
 He said: "Remember, the NSA works for the president. Through his national security advisers he knew or should have known." 
 
 Asked about the propriety of such surveillance, Issa answered: "If what you do in Germany helps the Germans, then fine. But you don't spy on a head of state." 
 
 Mike Rogers, the Republican chair of the House intelligence committee, was more bullish in defending surveillance practices, criticising press coverage of the latest NSA revelations and arguing that Europeans were unaware of the extent of surveillance conducted by their own governments and had been misled by incorrect media reports about the nature of NSA activities. 
 
 He told CNN recent reports in France about the NSA's monitoring of millions of phone calls in the country were "100% wrong". 
 
 "I would argue by the way, if the French citizens knew exactly what that was about, they would be applauding and popping champagne corks," he said. "It's a good thing – it keeps the French safe." 
 
 Going further, Rogers claimed that the emergence of fascism in Europe in the early 20th century could be partly explained by a conscious decision by the US not to monitor its allies. 
 
 "We said: 'We're not going to do any kinds of those things, that would not be appropriate," he said. "Look what happened in the 30s: the rise of fascism, the rise of communism, the rise of imperialism. We didn't see any of it. And it resulted in the deaths of tens of millions of people." 
 
 Rogers added: "Remember: sometimes our friends have relationships with our adversaries."

– In 2013, after Edward Snowden dropped his NSA bombshell, President Obama called for an end to spying on certain world leaders. But Benjamin Netanyahu and other Israeli bigwigs remained on the "keep an eye on" list for "compelling national security" reasons, current and ex-US officials tell the Wall Street Journal. Included in the US spying sweep were conversations between Israeli officials and US lawmakers and American-Jewish groups, which, as one senior US official tells the paper, resulted in an "Oh s--- moment" that the executive branch would be nailed for spying on Congress. The White House, though, felt the info necessary to rebut lobbying Netanyahu might do against a US-Iran deal; still, it was "wary of a paper trail stemming from a request." And so "we didn't say, 'Do it' [to the NSA]," a senior US official tells the Journal. "We didn't say, 'Don't do it.'" Instead, the administration more or less let the NSA share whatever info it saw fit, and the NSA did just that, reportedly following tight mandates about spying on communications "to, from, or about" Americans, the paper notes. For example, the agency took out names of individual lawmakers and any personal info in reports it submitted to the White House and also omitted any "trash talk" about the administration, officials tell the Journal. At least one presidential candidate isn't surprised by the revelations. "This administration views Congress, Republicans, and sometimes even Democratic members of Congress as their enemy," Ted Cruz tells CBS News. "At times, it seems like they view the American people as their enemy." A National Security Council spokesman, however, tells CBS, "[W]e do not conduct any foreign intelligence surveillance activities unless there is a specific and validated national security purpose. This applies to ordinary citizens and world leaders alike."
