Conservatives are calling for Republicans in Congress to fulfill their campaign promises by supporting President Donald Trump’s spending proposal and to not enact amnesty in a year-end deal with Democrats.

A letter released Monday and signed by 44 conservative leaders explains that Virginia is “in ruins” after Republican losses at both the statewide and local level earlier this month. The leaders warn that the Republican majority in the House could be in jeopardy next.

“Your consultants and managers are out of excuses—and your conservative grassroots are running out of both patience and time,” the letter states. “So stop panicking and start legislating.”

The letter criticizes Republicans—who control both chambers of Congress—for making deals with the Democrats that hurt the GOP agenda in the long run. The letter warns Republicans not to fall in line with the agenda of Senate Minority Leader Chuck Schumer, D-N.Y., and House Minority Leader Nancy Pelosi, D-Calif.

Congress, the letter says, is heading toward a path in December that will lift “the domestic spending caps set in 2011 Budget Control Act (BCA) debt deal, allowing ballooning trillion dollar deficits in future years,” will give amnesty to the illegal immigrants who came as minors, will give “billions of dollars of bailouts” to insurance companies, and will only allot a small amount of funding for Trump’s border wall.

The letter is signed by the leaders of many conservative organizations, such as Colin Hanna, president of Let Freedom Ring; Jenny Beth Martin, chairman of Tea Party Patriots Citizens Fund; and Ginni Thomas, wife of Justice Clarence Thomas, of Liberty Consulting.

The letter also calls on Congress to repeal Obamacare in 2018 and says that what happened in Virginia was just an “aftershock” with more to follow.

Rick Manning, president of Americans for Limited Government, an organization that works to prevent the expansion of government, helped write the letter and also signed it. He said the circumstances behind the current Congress is disappointing as they have failed on their platform promises, and because of this, the Republican majority is in danger.

“The truth is this letter is designed to really reach a hand out to the Republicans who are floundering and say, ‘We’ll help you find your way back to where you were when you got elected,’” Manning said. “We’re hoping they’ll pull up alongside us, and we’ll be able to fulfill the promise of the Republican majority, which was a limited government promise.”
