More than 70 Republicans have signed a letter to the party’s national committee head urging him to stop helping Donald Trump’s campaign. They said Trump’s “divisiveness” and “incompetence” risked drowning the party in November’s election. The letter said that the party should instead focus on protecting vulnerable candidates in elections to the senate and the House of Representatives. Former members of congress are among the signatories of the letter. Reacting to the move, Trump said he was not concerned that the party could cut him off. Time magazine on Thursday reported that RNC Chairman Reince Priebus had threatened to withdraw funding from the trump campaign, and instead direct it to congressional campaigns. Trump denies that this conversation ever took place. In recent weeks, several leading republicans have deserted trump over his outspoken attacks.
