President Donald Trump's niece didn't hold back in an interview on Thursday when discussing the administration's handling of the Jeffrey Epstein files. Mary Trump, a psychologist and author, has often criticized her uncle's administration and the president himself. During an interview with CNN's Erin Burnett on Thursday, Mary Trump said her uncle's statements about the Epstein files, and the Trump Department of Justice's efforts to obfuscate the files that have been released, show that Trump "has been acting like a guilty man." "The fact of the matter is that, Donald, since the Epstein files have become an issue since he got back into the White House, he has been acting like a guilty man," Trump said. "And I think much more troubling is the extent to which the DOJ, which currently is acting as if it's his personal defense firm, is covering for him because the truth of the matter is, if he had no involvement in anything suspect, he more than anybody else would want full transparency."The Trump administration has only released about 2% of the Epstein files in its possession, according to reports. And the files that is has released have undercut several claims Trump has made about his relationship with Epstein. For instance, Trump has claimed to have no knowledge of Epstein's crimes, yet called the Palm Beach Police Department with insider knowledge of Epstein's activities, according to one file.
