Jimmy Kimmel expressed his appreciation on Monday after Sen. Susan Collins said she does not plan to vote for the Graham-Cassidy proposal that would dismantle the Affordable Care Act, dubbed Trumpcare.

“Thank you @SenatorCollins for putting people ahead of party,” Kimmel tweeted. “We are all in your debt.”

Collins joins Sens. John McCain, R-Ariz., and Rand Paul, R-Ky., as Republican “no” votes against the bill that would repeal Obamacare. This prevents the party from hitting the needed 50 votes, unless one of the dissenters has a change of heart.

Kimmel previously hailed McCain as a “hero” for announcing that he will not vote for the bill.

The late-night host has been an outspoken critic of the legislation in recent days, saying that Sen. Bill Cassidy lied to him about his health care plans during a previous visit to “Jimmy Kimmel Live!”

Kimmel became part of the health care debate earlier this year when he announced that his newborn son, Billy, had undergone open-heart surgery, leading the ABC personality to emphasize the importance of accessible medical treatment.
