The ousted White House staff secretary worked with the same temporary clearance Kushner had at the time, and Kushner reportedly had a dispute with John Kelly when the chief of staff tried to address the scandal by yanking security clearance from anyone who didn't have full clearance.
Abbe Lowell, who has represented Kushner in the Russian Federation investigation, told CNN's Wolf Blitzer that questions asked of Kushner during the April interview were "the appropriate topics that Bob Mueller and his team were looking at".
Lowell said Kushner answered all questions and "is looking forward to continuing the work the president has asked him to do". 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 Federal Bureau of Investigation.

The special counsel's questioning focused on Kushner's work with Trump and did not include topics such as Kushner's personal finances or those of his family business, Kushner Companies, according to the person. "Since then, he has continued this entire cooperation, offering a lot of paperwork and sitting for hours of interview with congressional committees and offering quite a few paperwork and sitting for 2 interviews with the Workplace of Particular Counsel".
"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 in a statement.
Mr Kushner, who serves as Mr Trump's adviser on the Middle East, had his access downgraded in February pending the completion of background checks.
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.
Kushner's initial SF-86 form did not mention any foreign contacts, though he quickly supplemented it to indicate that he would provide that information.
