WASHINGTON — President Trump returned to Twitter on Wednesday morning and said that Republican senators must keep their promise to America, but he was not specific about which promise on health care legislation he was discussing.
Republicans have been promising for seven years to undo President Barack Obama’s signature Affordable Care Act, but that pledge hit a wall on Tuesday when Republicans could not get enough support from their senators to move forward with a proposal.
To move the effort ahead, Mr. Trump invited Republican senators for lunch on Wednesday to discuss health care legislation.
In another tweet on Wednesday, Mr. Trump said Republicans did not discuss “how good” their health care proposal was and promised it would get better during their lunch.
Mr. Trump’s message about health care has changed in the last 24 hours. On Monday night, he tweeted that Republicans should repeal the Affordable Care Act without waiting to agree on what should replace it.
Early Tuesday morning, Mr. Trump said on Twitter that Mr. Obama’s legislation should just be left to fail. At that point, he said, legislators would present a better plan.
The prospect of repealing the health care law appeared to be doomed on Tuesday when an 11th-hour effort to force a vote on the matter failed and three Republican senators said they would not vote to repeal the law without a replacement.
Mr. Trump has never been completely engaged with the health care repeal and replace efforts after his initial foray with House members in April failed.
