Conservative talk show host Joe Walsh, a Republican challenger to Donald Trump in the 2020 GOP primary, was banned for 12 hours from Twitter after posting that FBI Director Christopher Wray should punch the president in the face, the Washington Examiner reported.

“.@realDonaldTrump last night called Christopher Wray & other FBI leaders ‘scum.’ Wray is a patriotic public servant. To defend his and the agency’s honor, he should resign immediately. And then he should punch Donald Trump in the face,” Walsh said in the now-deleted tweet.

Walsh’s campaign manager, Lucy Caldwell, posted screenshots of an email from Twitter that said the tweet had violated rules against “abuse and harassment.”

“… he wrote this and then got banned, no doubt thanks to the Trump Twitter mob,” Caldwell posted with the hashtag “#BeBrave.”

Walsh, who voted for Trump, continued blasting the president on Twitter on Thursday.
