"Everyone in the White House is grateful for these valuable contributions to furthering the president's agenda", Kelly said of Kushner.
"As I told Jared days ago, I have full confidence in his ability to continue performing his duties in his foreign policy portfolio including overseeing our Israeli-Palestinian peace effort and serving as an integral part of our relationship with Mexico", Kelly said.
"First of all, I'm not aware of any red flags, and I think it's irresponsible to suggest that without having seen any individual's file", she said.
Almost a year into the Trump administration, senior-level staffers - including Ivanka Trump and Jared Kushner - remained on interim clearances even as other senior advisers were granted full security access, according to information obtained by CNN from a USA government official.
That new policy would presumably affect Kushner, who now holds an interim TS/SCI security clearance that has been pending since he joined the White House more than a year ago.
Over the past 13 months Kusher's clearance has given him access to classified information including the president's daily briefing and intelligence summary.
At one time his portfolio expanded to include the USA relationships with China and Japan and a host of domestic priorities, including infrastructure, trade and economic development.
Abbe Lowell, Kushner's lawyer, said the senior official "has done more than what is expected of him in this process".
That included executives of Anbang Insurance, a company that's closely tied to the Chinese government - so much so, in fact, that Anbang's attempt to purchase a hotel near a United States naval base in San Diego in 2016 was reportedly called off after U.S. national-security officials voiced their opposition to it. Kelly added that Kushner would still have access to information with the new security clearance process in place. Kushner is reportedly being investigated by Special Counsel Robert Mueller, but his several amendments to his background application means he is actually safe from Kelly's directive, for now.
Kelly announced the change in a memo to White House counsel Don McGahn, after coming under criticism for his handling of domestic abuse allegations against former White House staff secretary Rob Porter. Kelly has been the subject of criticism in that time over revelations that Porter remained on staff for months in spite of the Federal Bureau of Investigation flagging the allegations of domestic abuse to the White House. The White House has repeatedly refused to comment on the clearances of senior staffers.
