In a letter to members of the National Rifle Association, Rep. Mark Meadows (R-NC) and Rep. Diane Black (D-NC), members of Congress are urging the NRA to oppose the Affordable Care Act.

“Our country is in danger of being plunged into a catastrophic and irreversible financial collapse,” Meadows and Black wrote.

“With the stroke of a pen, the NRA will make sure we don’t.”

Meadows and Blackburn also urged the NRA not to support the House Republican plan to overhaul Medicare and Medicaid, and to reject the American Health Care Act, the GOP plan to replace Obamacare.

“There are few more devastating, devastating things than having your health insurance canceled because of Obamacare,” Meadows said.

“The Republican plan will cause massive hardship for our citizens and is likely to put our country at risk.”

The NRA did not immediately respond to a request for comment.

Black and Meadows’ letter comes after House Republicans in March released their draft legislation to overhaul Obamacare.

It calls for expanding coverage to include people with preexisting conditions and for expanding Medicaid coverage to more people, while removing Obamacare’s insurance subsidies and defunding Planned Parenthood.

“A vote for the Republican proposal will only worsen the problems we are facing,” Black and Blackburn said in their letter.

“By voting to proceed with the House bill, we hope to get the Republican Party to act to prevent us from having to deal with the catastrophic consequences of a GOP plan that would result in a catastrophic financial collapse and lead to a permanent state of permanent emergency.”

The bill is currently under consideration in the House and Senate, with Republicans currently controlling both chambers of Congress.

A draft of the bill has also been leaked, showing it would give states more flexibility to expand Medicaid coverage and would leave the federal government with the task of administering Medicare and Obamacare.
