A GOP senator on Sunday warned his colleagues in the House not to “walk the plank” and pass a bill scuttling ObamaCare because it is headed for failure in the Senate and could even risk their majority rule.

“I would say to my friends in the House of Representatives with whom I serve, ‘Do not walk the plank and vote for a bill that cannot pass the Senate and then have to face the consequences of that vote,'” Sen. Tom Cotton said on ABC’s “This Week.”

Cotton (R-Ark.) said the legislation House Republicans introduced last week to repeal and replace former President Obama’s signature healthcare legislation can be fixed but “it’s going to take a lot of carpentry on that framework.”

“As it’s written today, this bill in the House of Representatives cannot pass the Senate. And I believe it would have adverse consequences for millions of Americans,” he said.

He urged GOP House members to go slow on the bill, fearing it could lead to higher insurance premiums and price people out of the healthcare system.

“I’m afraid that if they vote for this bill, they’re going to put the House majority at risk next year,” Cotton said.

The GOP holds majorities in the Senate and the House leading into the 2018 midterm elections.
