President Trump spent a good chunk of Mother's Day retweeting posts critical of former President Barack Obama, and at one point accused him of committing "the biggest political crime in American history, by far."
During a Monday press conference, Trump was asked to elaborate on the accusation. He replied with a series of vague claims, noting that "ObamaGate" had been going on for a long time before the White House transition. "Some terrible things happened," he said.
When pressed again to say what crime he accused Obama of committing, the president said the "crime is very obvious to everybody" — except for Washington Post readers — but he again failed to dive into specifics. For some clarity on Trump's allegations read more at Vox. Tim O'Donnell
