Donald Trump pulled the bill just second before the vote
House Speaker Paul Ryan sensationally cancelled the vote for a second time today after it was made clear the President had not secure the required 215 votes.
Amid a chaotic scramble, Mr Ryan met with Donald Trump at the White House to discuss the numbers.
But the bill was pulled from the House floor after hours of debate and just minutes before the vote was due to take place – despite Mr Trump issuing an ultimatum over the vote on Friday.
The US House of Representatives has now adjourned, and it is unclear when members will return.
Although Trump told the Washington Post: "We just pulled it."
Mr Trump has revealed the bill is not going to come up again in the near future – but may revisit it sometime later this year.
Without the bill's passage in Congress, former President Barack Obama's signature domestic policy achievement would remain in place despite seven years of Republican promises to dismantle it.
Repealing and replacing the 2010 Affordable Care Act – known as Obamacare – was a top campaign promise by Trump in the 2016 presidential election.
And now he is facing fierce abuse online, as social media users repeat his campaign pledges from last year.
In one retweeted post from last year, Mr Trump said: "We will immediately repeal and replace ObamaCare – and nobody can do that like me. We will save $'s and have much better healthcare!"
