Senior White House adviser Jared Kushner declared that all the "crazy" accusations leveled against him have “turned out to be false" in a rare TV interview.

Sitting down for an interview with Fox News host Laura Ingraham, President Trump's son-in-law was asked about a White House security clearance controversy that has ensnared him and others.

“Over the last few years that I’ve been here, I’ve been accused of all different types of things, and all of those things have turned out to be false,” Kushner said during the interview which aired Monday. “We’ve had a lot of crazy accusations, like, that we colluded with Russia. I complied with all the different investigations, whether it be the Senate, the House, the special counsel. I’ve sat for nearly 20 hours of interviews with them.”

The interview comes more than a week after special counsel Robert Mueller concluded his yearslong Russia investigation and sent his report to the Justice Department. According to a summary Attorney General William Barr sent to Congress, Mueller found no collusion between the Trump campaign and Russia.

The summary did not, however, provide insight on whether Trump or any of his associates were compromised by Russia.

Kushner's contacts with Russians during the 2016 presidential campaign have come under intense scrutiny since he entered the White House, including by Mueller and congressional investigations.

Kushner, who is married to Trump’s daughter Ivanka Trump, also emphasized that he has followed the guidance of the Office of Government Ethics since coming to Washington, D.C.

“When I came to Washington, I had a very successful business career,” Kushner said. “I had extensive holdings. I disclosed all of my holdings for the Office of Government Ethics, and what I did with them is they told me what to divest, what to keep, what rules to follow. We followed all that.”

Just hours before the interview aired on Fox News, House Democrats announced that a career White House security office employee turned to them as her “last hope” to divulge details on more than two dozen denials for security clearances have been reversed during the Trump administration.

The whistleblower, Tricia Newbold, claimed she encountered retaliation for cautioning her superiors that the clearances “were not always adjudicated in the best interest of national security.”

“I feel that right now this is my last hope to really bring the integrity back into our office,” she told the House Oversight Committee.

The committee, led by Chairman Elijah Cummings, D-Md., is examining the security clearances of Kushner and Ivanka Trump, and is prepared to start issuing subpoenas as part of the investigation. Media reports this year indicate that Trump instructed then-chief of staff John Kelly to approve a top secret security clearance for Kusnher.
