Speaking Tuesday on Boston Public Radio, CNN’s John King speculated that President Donald Trump, in a Tuesday afternoon tweet, was reacting to worries from within the GOP that his constant questioning of vote-by-mail could supress Republican voter turnout in November.

President Trump appeared to backpedal from his stream of attacks against mail-in voting on Tuesday, writing in the tweet that "Whether you call it Vote by Mail or Absentee Voting, in Florida the election system is Safe and Secure, Tried and True.”

"Republicans have been coming to the president saying, 'Sir, you need to stop attacking this, because there are a lot of people out there who listen to you,’” King, CNN's chief national coorespondent, said. “And if you are a Trump voter, and the president keeps saying ‘don’t vote by mail,’ and then you get worried about the coronavirus closer to the election and you don’t have a mail-in ballot, well, then he will lose. He will suppress Republican turnout by attacking something that is going to happen in almost every state."
