Joe Biden is hammering President Donald Trump as a dishonest, failed president. It’s part of Biden’s aggressive counter strategy ahead of Monday’s Iowa caucuses. The former vice president is fending off a new onslaught of Republican attacks over his son’s business overseas as Trump’s Senate impeachment trial continues in Washington. In Iowa on Thursday, Biden said Trump must be defeated in November. He said he doesn’t believe “we are the dark angry nation that Donald Trump sees in his tweets in the middle of the night.” Biden and Trump are both campaigning in Iowa on Thursday.
