Hillary Clinton calls Trump 'illegitimate president' and 'corrupt human tornado'

Clinton, who ran against Trump in 2016, added that she supports the House of Representatives' newly launched impeachment inquiry. "My view is that, given the latest revelation, which is such a blatant effort to use his presidential position to advance his personal and political interests, there should be an impeachment inquiry opened," Clinton told CBS News. "And I think, sadly, there are a number of grounds. But this one is incredibly troubling."
