President Trump called former Vice President Joe Biden “another low I.Q. individual” for accidentally admitting in a speech on Saturday that he was entering the Democratic presidential race. “Joe Biden got tongue tied over the weekend when he was unable to properly deliver a very simple line about his decision to run for President. Get used to it, another low I.Q. individual!” Trump tweeted Monday. Speaking at a Delaware Democratic Party fundraiser, Biden defended his political stance against critics who say he would be a moderate if he ran among the current crop of Democratic candidates.
