President Trump’s recent suggestion that North Carolina voters should cast multiple ballots has run afoul of Twitter’s election integrity rules. In a series of tweets Thursday morning, the president elaborated on previous statements in which he encouraged Americans to vote twice to “check” vote-by-mail systems.

Trump made the initial comments in a local television interview Wednesday. “They will vote and then they are going to have to check their vote by going to the poll and voting that way because if it tabulates then they won’t be able to do that,” Trump said.
