US President Donald Trump has demanded a make-or-break vote in the House of Representatives on Friday on his troubled healthcare bill.
The American Health Care Act is meant to replace parts of President Barack Obama’s signature “Obamacare” law.
A vote on Thursday was delayed because of opposition from some Republicans.
Mr Trump reportedly told fellow Republicans that they had a choice between voting for his bill on Friday or being stuck with Obamacare for good.
The president made the warning during a closed-door meeting at the White House, US media reported.
A debate on the bill is now taking place in the House of Representatives, with a vote due later on Friday.
Republican and House Speaker Paul Ryan said: “For seven-and-a-half years we have been promising the American people that we will repeal and replace this broken law because it’s collapsing and it’s failing families, and tomorrow we’re proceeding.”
Chris Collins, a New York Republican who supports Mr Trump, said on Thursday evening: “The president has said he wants a vote tomorrow, up or down. If for any reason it is down, we are just going to move forward with additional parts of his agenda.”
Mr Trump kept up the pressure on Friday morning, tweeting: “After seven horrible years of ObamaCare (skyrocketing premiums & deductibles, bad healthcare), this is finally your chance for a great plan!”
Another tweet targeted the conservative Freedom Caucus, many of whose members have opposed the bill.
