Jared Kushner, President Trump's son-in-law and adviser, has been granted his permanent security clearance, a person briefed on the matter said on Wednesday, ending a period of uncertainty that had fueled questions about whether Mr. Kushner was in peril in the special counsel investigation. He is married to Ivanka Trump, the president's oldest daughter.
Kushner met with Mueller's investigators a second time in April and answered questions for seven hours, according to his attorney, Abbe Lowell.
Kushner, US President Donald Trump's son-in-law, was operating for more than a year with interim clearance amid concerns over his foreign contacts and financial entanglements.
That policy was ended in February by the White House.
Porter was forced to leave the Trump Administration in disgrace when his alleged domestic abuse of multiple women was revealed to the public.
Chief of Staff John Kelly ended lengthy temporary clearances for several elite West Wing staffers after the dismissal of former White House Staff Secretary Rob Porter, insisting that they must lose access to the government's most sensitive material while lengthy background checks wore on.
He said Kushner's clearance was decided by career officials in the intelligence community and the Federal Bureau of Investigation.
Mueller is investigating the Trump campaign's ties with Russian election meddling.
His financial situation has since improved markedly.
Mark Zaid, a national security lawyer, said people who lose their interim security clearances are often able to get them restored after a fuller investigation of the issues that caused concern for security officers.
But a law enforcement source told DailyMail.com that a major stumbling block was Kushner's failure, even on his re-submitted application, to mention the now-famous 2016 Trump Tower meeting attended by Russian lawyer Natalia Veselnitskaya.
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.
