(CNN) President Donald Trump's son-in-law and senior adviser, Jared Kushner, had his White House security clearance restored Wednesday, a person familiar with the matter said, after months of uncertainty stemming in part from his role in the ongoing investigation by special counsel Robert Mueller. 
 
 Kushner met with Mueller's investigators a second time in April and answered questions for seven hours, according to his attorney, Abbe Lowell. He had previously sat for an interview last November that was largely focused on former national security adviser Michael Flynn, who soon after pleaded guilty to charges of making false statements to the FBI. 
 
 These developments come as the Mueller's investigators appear to be trying to complete parts of their inquiry. 
 
 The Kushner team believes he is now finished with all ongoing inquiries, which also include the investigations by congressional committees, according to a person close to Kushner. 
 
 A spokesman for Mueller declined to comment. 
 
 "A year ago, Jared was one of the first to voluntarily cooperate with any investigation into the 2016 campaign and related topics," Lowell said in a statement. 
 
 "Since then, he has continued this complete cooperation, providing a large number of documents and sitting for hours of interviews with congressional committees and providing numerous documents and sitting for two interviews with the Office of Special Counsel. On each occasion, he answered all questions asked and did everything he could to expedite the conclusion of all the investigations." 
 
 Kushner was stripped of his interim clearance in February amid an overhaul of procedures governing access to the nation's most sensitive secrets following the resignation of Rob Porter, the President's staff secretary, who had been allowed to remain in his post for months despite allegations of spouse abuse. 
 
 The Mueller probe has also hung over Kushner's status in the White House, in part because some of the matters under investigation relate to his role during the campaign and the transition, including contacts with Russians, as well as events that occurred in the early months of the Trump presidency, such as the firing of former FBI Director James Comey

 White House officials have blamed the delay in Kushner receiving his security clearance on administrative backlogs normal to a new administration, as well as the complicated nature of his application. But Kushner's troubles were compounded at least in part because his initial security clearance application didn't list dozens of foreign contacts that he later included in updated submissions to the FBI. 
 
 Lowell disputed that the initial security clearance application played any role in the delay in Kushner receiving his final clearance. 
 
 "With respect with the news of his clearance being restored, as we stated before, his application was properly submitted, reviewed by numerous career officials and went through the normal process," Lowell said. "Throughout the process, Mr. Kushner has continued to work on a number of foreign policy and domestic issues with no interruption. Having completed all of these processes, he is looking to continue to do the work the President has asked him to do." ||||| (CNN) Jared Kushner, who has worn dueling hats for more than a year as President Donald Trump's senior adviser and son-in-law, has been stripped of his access to the nation's top secrets, officials said Tuesday after his security clearance was downgraded. 
 
 Kushner, along with other White House officials who had been operating on interim clearances, had their access altered last week after chief of staff John Kelly stipulated new changes to the security clearance system. 
 
 Aides who previously operated on "top secret/sensitive compartmented information" interim clearances saw their access changed to "secret," a classification for less sensitive material. The lesser "secret" clearance allows access to far fewer government secrets. It would prevent Kushner from accessing the Presidential Daily Brief, the collection of top secret material prepared for the commander in chief every day. 
 
 Dozens of White House officials have operated on interim clearances since Trump took office more than a year ago. Kelly had grown frustrated with the high number of aides without permanent access and has worked to shrink the number of temporary clearances. He issued a memo last week spelling out changes to the system, which gained new scrutiny after domestic abuse allegations against former aide Rob Porter surfaced this month. 
 
 In the February 16 memo, Kelly stated that White House officials who have been operating on interim clearances since last June would have their temporary clearances discontinued. That included Kushner, who has taken on a wide portfolio as senior adviser, including sensitive foreign policy matters. Asked on Friday whether he would grant Kushner an exemption from the new mandate, Trump said it would be Kelly's decision. 
 
 The White House has refused to detail the status of Kushner's clearance. In a statement, Kushner's attorney Abbe Lowell wrote: "Mr. Kushner has done more than what is expected of him in this process." 
 
 "Those involved in the process again have confirmed that there are dozens of people at Mr. Kushner's level whose process is delayed," Lowell wrote. "No concerns were raised about Mr. Kushner's application. As General Kelly himself said, the new clearance policy will not affect Mr. Kushner's ability to continue to do the very important work he has been assigned by the President." 
 
 Kushner is accepting the decision about his security clearance and "will not ask for special permission" from the President, one person familiar with the situation says. 
 
 Politico first reported the security clearance downgrade. At the White House on Tuesday, press secretary Sarah Sanders said Kushner's work would continue apace. 
 
 "He is a valued member of the team and will continue to do the important work he has been doing since he started in the administration," Sanders said.

 White House officials have been working over the past week to identify a way for Kushner to continue pursuing his portfolio of issues -- including on the Middle East and China -- that would avoid forcing Trump to personally intervene. Officials have expressed worry that Trump's personal involvement could create problems within the West Wing and with Kelly. 
 
 The security clearance issue has caused a rift between Kushner and Kelly, multiple source familiar with the matter say. The President is aware of the tensions between the two men over the matter, a person familiar with his thinking said. 
 
 Republican sources close to the White House said the clearance downgrade could undercut Kushner's ability to influence policy decision-making in the West Wing. Without a top-level clearance, Kushner will be unable to attend meetings where the most sensitive national secrets are discussed. 
 
 It's not clear how long the diminished security clearance will last. The FBI is expected to wrap up Kushner's background check within a month, a person familiar with the situation said, adding that the FBI would hand the findings to the White House for it to make the ultimate decision on Kushner's clearance. 
 
 A "surge" of FBI agents have been tasked with processing a backlog of background investigations into Trump administration officials seeking security clearances, law enforcement sources said. Agents are "churning and burning" to complete the required checks, one official with the matter said. "We're trying to help the process ASAP." 
 
 Meanwhile, White House officials say they've noticed an uptick in the pace of top secret security clearance decisions coming from the White House Personnel Security office. That's the department tasked with taking the FBI background check and determining whether a clearance should be granted. 
 
 One law enforcement source said agents in two Washington-based squads tasked with completing background checks are "inundated" with "thousands of people" across the government who still require background investigations before receiving permanent security clearances. 
 
 "We thought we had an adequate number of individuals assigned. We realized we need to up our ante and get this off our plate," the official said. "It's an arduous process that they go through. You can only do so much in 24 hours."

 In the February 16 memo, Kelly wrote that in the wake of the Porter scandal he "convened a number of after-action meetings," including with senior FBI leadership, to discuss the security clearance process. 
 
 "They have offered to assist us with reviewing and improving our protocols and we have accepted their assistance," Kelly wrote. 
 
 He noted that even before the Porter scandal he had directed the Personnel Security office to make "better use of existing staff" and hire "additional staff." 
 
 Before Kelly issued his memo, White House and Justice Department officials convened a conference call to see whether some of the outstanding background check investigations for officials on interim clearances could be completed quickly. That included Kushner, according to a person familiar with the call. In his memo, Kelly stated that all interim clearances would be discontinued in a week's time. 
 
 A separate conversation took place last week between Deputy Attorney General Rod Rosenstein and White House counsel Don McGahn about Kushner's clearance. Rosenstein explained on the call the clearance process for Kushner was still ongoing, according to a source familiar with the matter. 
 
 "The deputy attorney general has not referenced to the White House any specific concerns relating to this individual's security clearance process," Justice Department spokeswoman Sarah Isgur Flores said.
– It took a while, but presidential son-in-law and top adviser Jared Kushner has received his permanent security clearance, reports the New York Times. Kushner had been stripped of his top-level clearance in February as the White House tightened policy in the wake of the Rob Porter scandal, notes CNN. But the FBI recently completed its background check into Kushner's financial history and foreign business dealings and found no red flags, reports the Washington Post. "As we stated before, his application was properly submitted, reviewed by numerous career officials and underwent the normal process," says Kushner attorney Abbe Lowell. "Having completed all of these processes, he’s looking forward to continuing to do the work the president has asked him to do.” Lowell also revealed that Kushner has voluntarily sat for two long interviews with Robert Mueller's team, answering questions about Michael Flynn and Kushner's work on the campaign and in the White House.
