Rep. Ron DeSantis, R-Fla., argued Monday that President Trump should follow through on his weekend threat and cancel all subsidies that federal lawmakers get to buy insurance under Obamacare.

He also said killing lawmakers' subsidies might be the best way to kill Obamacare.

"I think if he moves swiftly on it, I think you'd see a lot of these members and senators, they would want to work to repeal Obamacare very quickly," DeSantis said on Fox News.

Trump tweeted Saturday that if Congress can't pass a healthcare bill, "bailouts for members of Congress will end very soon!"

Trump reiterated the point again on Monday, when he asked why Congress should be getting a break that others aren't.

"If ObamaCare is hurting people, & it is, why shouldn't it hurt the insurance companies & why should Congress not be paying what public pays?" he asked.

Lawmakers and their aides get a government subsidy under Obamacare in the form of an employer contribution.

"I decline the subsidy," DeSantis said. "It's not right and I don't take it because I don't think it's lawful."

"I think the president would be absolutely within his rights to cancel the Obama rule that conferred this subsidy on Congress," he added.
