President Trump again signaled his opposition to a bipartisan deal to stabilize Obamacare, saying Wednesday he doesn't approve of any proposal that will "enrich the insurance companies."

"We're going to see the bipartisan, and Lamar Alexander's working on it very hard from our side, and if something can happen that's fine," Trump told reporters of talks to stabilize Obamacare. "But I won't do anything to enrich the insurance companies, because right now the insurance companies are being enriched. They've been enriched by Obamacare like nothing anybody's ever seen before. I'm not going to do anything to enrich the insurance companies."

Sens. Lamar Alexander, R-Tenn., and Patty Murray, D-Wash., the leaders of the Senate Health, Education, Labor, and Pensions Committee agreed to a deal Tuesday to fund Obamacare's cost-sharing reduction subsidies for two years.

Trump abruptly ended the cost-sharing reduction subsidies last week, which go to insurance companies to reimburse them for lowering out-of-pocket costs for low-income Obamacare customers.

The president praised the bipartisan work being done by Alexander and Murray after the deal was announced Tuesday, and appeared to back the plan, but said on Twitter on Wednesday morning he opposed it.

"I am supportive of Lamar as a person & also of the process, but I can never support bailing out ins co's who have made a fortune w/ O'Care," Trump tweeted.

Conservatives have called the cost-sharing reduction subsidies "bailouts" because of the billions of dollars given to insurers. The federal government paid insurers $7 billion last year in cost-sharing reduction subsidies.
