A broad swath of Republicans have penned an open letter to the Republican National Committee requesting that Donald Trump no longer receive money to help with his presidential campaign.

The letter urges RNC Chairman Reince Priebus to immediately stop spending any of the national party's available funds on Trump and instead funnel more money into congressional races across the country.

"We believe that Donald Trump's divisiveness, recklessness, incompetence, and record-breaking unpopularity risk turning this election into a Democratic landslide, and 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," reads the letter, which goes on to claim Trump's chances of making it to the White House are "evaporating by the day."

Nearly 20 of the individuals behind the letter previously worked for the RNC, while other signatories include former members of Congress who have publicly declared their opposition to Trump.

One of the co-signers, former New Hampshire Sen. Gordon Humphrey, had recently urged Priebus to call a meeting of RNC members and invoke Rule 9, which allows Republicans to replace their existing presidential nominee in the event of a death, resignation or other circumstance.

The letter is currently being circulated to high-profile Republicans and will be sent to Priebus next week. It had garnered more than 70 signatures by Thursday from "people who want the party to protect its majorities in the Senate and the House," according to longtime GOP operative Andrew Weinstein.

Trump finalized a joint fundraising agreement with the RNC in mid-May, shortly after he became the presumptive Republican presidential nominee. The billionaire raised $80 million last month, 80 percent of which came through direct donations to his campaign while $16 million was raised at fundraisers organized by the RNC and can be dispersed to help with congressional races.

A spokesman for the RNC did not return the Washington Examiner's request for comment.
