years. so let's continue to investigate that. >> and trump's retweet of this conspiracy theory is not an isolated incident. it's the president using his powerful megaphone to share conspiracy theories and other falsehoods. going back even before he was president, one of the ways the president rose on the political right, of course, was sharing the false conspiracy theory that president barack obama was not born in the united states. even after the former president shared his birth certificate. and then as a candidate for president, trump shared the conspiracy theory linking ted cruz's father to the assassination of jfk. and once he became president, among many other conspiracy theories, the president suggested that former president obama had wiretapped his phones during the 2016 campaign. so all very much part of a pattern the president continuing that this weekend. >> quite the litany there. jeremy diamond, thank you so much. let's talk more.
