“Given the catastrophic impact that Donald Trump’s losing presidential campaign will have on down-ballot Senate and House races, we urge you to immediately suspend all discretionary RNC support for Trump and focus the entirety of the RNC’s available resources on preserving the GOP’s congressional majorities,” a draft of the letter states.

The RNC has denied several reports that Chairman Reince Priebus has warned Trump to get his act together or risk losing support from the national party and says it is not considering abandoning the nominee at this point.

Trump and the RNC have a joint fundraising agreement in place, although last week Trump mused about how the RNC would suffer if it cut ties with him because he’d stop raising money for the national party.

The billionaire raised more than $80 million last month but has been slow to spend it. Trump is overly reliant on the RNC for staffing in battleground states and has not invested any money on the television airwaves.

Republicans interviewed by The Hill say they don’t expect Priebus or RNC officials would ever publicly run against Trump.

The letter signed by Rigell and Ribble is being drawn up by Andrew Weinstein, a former spokesman for then-House Speaker Newt Gingrich (R-Ga.) and a communications staffer on Bob Dole's 1996 presidential campaign.

It has 123 total signatories, including 10 former House or Senate members and 27 former RNC staffers.
