In a letter signed by more than 70 Republicans, the GOP’s National Committee head is being urged to stop funding Donald Trump’s campaign.
The signatories said Donald Trump’s “divisiveness” and “incompetence” risked drowning the party in November’s election.
The letter said that the GOP 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.
“We believe that Donald Trump’s divisiveness, recklessness, incompetence, and record-breaking unpopularity risk turning this election into a Democratic landslide,” said a draft of the letter published by Politico.
“Only the immediate shift of all available RNC resources to vulnerable Senate and House races will prevent the GOP from drowning with a Trump-emblazoned anchor around its neck.”
The letter added: “This should not be a difficult decision, as Donald Trump’s chances of being elected president are evaporating by the day.”
Reacting to the move, Donald Trump said he was not concerned that the party could cut him off.
“All I have to do is stop funding the Republican Party,” he said.
According to a Time Magazine report on August 11, RNC Chairman Reince Priebus had threatened to withdraw funding from the Trump campaign, and instead direct it to Congressional campaigns.
Donald Trump denies that this conversation ever took place.
The Republican presidential nominee has endured 10 days of negative headlines after a string of controversial comments.
In recent weeks, several leading Republicans have deserted Donald Trump over his outspoken attacks.
Polls suggest support for Donald Trump has been falling in key battleground states in recent weeks.
