Sen. Lamar Alexander, R-Tenn., pledged on Wednesday to improve a bipartisan deal to fund Obamacare payments after President Trump criticized those payments as a "bailout" to insurance companies.

"I will work with the president to see if we can make it even stronger," he said.

Alexander's response is an attempt to salvage a bipartisan deal that Trump appeared to have scuttled in an early-morning tweet Wednesday. Trump has encouraged Alexander to make a deal on the payments, which Trump cut off last week, but Trump then tweeted Wednesday he couldn't back his proposed deal, which would see payments continue to insurance companies for two more years.

Alexander tweeted Wednesday that the deal with Sen. Patty Murray, D-Wash., has "strong language" to ensure the money goes to consumers.

The deal announced Tuesday includes several reforms to Obamacare including expanding catastrophic plans and giving states more flexibility to waive Obamacare regulations.
