Transcript for Still no answer on what led to Trump's weekend Twitter tirade
First right to that new fallout from president trump's stunning claim accusing president Obama of wiretapping phones in trump tower before the election. All this without offering proof. The former administration is denying accusations. Three big question, number one, did president Obama order an illegal wiretap at trump tower.
