But after the amendment failed, Senate Majority Leader Mitch McConnell voiced his frustrations: "This is clearly a disappointing moment", McConnell said.
The goal of passing such legislation would be to get something, anything, out of the Senate, so that talks could begin with House Republicans who passed their own more comprehensive repeal-and-replace bill in early May.
"I'd rather get out of the way and let it collapse than have a half-ass approach where it is now our problem", Graham said. "Watch!" Mr. Trump posted on Twitter.
The US Senate voted against an amendment to partially repeal Obamacare. It provided health insurance to millions of previously uninsured Americans.
No one, including Senate Republicans, can answer that with any confidence.
On Friday morning, as the US Senate Republicans looked on grim-faced, senator John McCain walked over to a clerk keeping a count of votes, and signalled a "No" with his thumb held down, bringing down a legislation moved by his party and backed by President Donald Trump to partly overhaul the current healthcare law.
Sen. John McCain didn't like what he heard.
McCain arrived on the Senate floor just after midnight, when debate on the "skinny" bill ended. Then on Wednesday, a straightforward repeal measure failed 55-45 with seven Republicans joining Democrats in voting "no", even though almost identical legislation had passed Congress two years earlier. Trump had criticized Murkowski, tweeting that she had let down the Republican Party and the country.
Republican Senators Susan Collins and Lisa Murkowski voted against the "skinny repeal" bill.
"It's time to turn the page", said Senate Minority Leader Charles Schumer of NY. Insurers nationwide would also take decisions accordingly of whether they would leave the ObamaCare exchanges or stay in it, reports said. Dianne Feinstein, D-Calif.
"Wait for the show", McCain, whose 2008 presidential campaign famously saw him billed as a "maverick", told reporters as he headed to the Senate floor.
"Skinny repeal is equal to full repeal.it's a Trojan horse", Schumer said. "We told our constituents we would vote that way, and when the moment came-when the moment came", he paused, "most of us did".
"It is time to move on", McConnell said. "This was a heavy lift". "I believe we shouldn't make that same mistake again". The Republican majority in Congress were hopeful of repealing the ACA, something which they have been voting against since 2011.
