Who Leaked Trump Tax Returns? President Doesn't Know How It Happened

Amid speculation that Donald Trump leaked his 2005 tax returns, the president said Wednesday he has "no idea" how investigative journalist David Cay Johnston got hold of the document. On Tuesday night, Johnston shared the tax returns document with MSNBC host Rachel Maddow, who, in turn, made the details public on her show. Trump made the clarification in an interview on Fox News' show "Tucker Carlson Tonight." He called the publishing of the tax records illegal.
