Washington (CNN) Jared Kushner, a White House adviser and President Donald Trump's son-in-law, defended his security clearance Monday, saying all the accusations against him during the past two years have turned out to be false.

"Over the last two 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 told Fox News.

Earlier Monday, CNN reported that a White House staff member had told House investigators that senior officials have overruled concerns raised about 25 individuals whose security clearances were initially denied over a range of disqualifying issues, and warned of the grave implications to national security, according to a senior Democratic lawmaker. The concerns included fears about foreign influence and potential conflicts of interests.

A source familiar with the case told CNN that Kushner and Ivanka Trump, Trump's daughter and a White House adviser, are on the list of 25 individuals.

"We've had a lot of crazy accusations, like that we colluded with Russia," Kushner told Fox and said he had "complied with all the different investigations" and had sat for nearly 20 hours of interviews.
