House Republicans spent most of Thursday — and, really, most of this week — trying drum up enough support to pass their replacement of Obamacare, the American Health Care Act. However, as of Thursday afternoon, both the future of the bill and the time lawmakers would formally vote on it remained unclear.

A Politico reporter tweeted there would not be a vote on the ACHA Thursday, citing an anonymous GOP source and noting that it was "still possible tomorrow."

The vote was originally set for Thursday because it was the seventh anniversary of former President Barack Obama's 2010 signing of the Affordable Care Act. Even President Donald Trump's press secretary, Sean Spicer, said he was "hoping to make this the last anniversary Americans will have to endure Obamacare." And though Spicer vowed Thursday that "it's going to pass," rumors spread all day that the vote would be delayed.

"It didn't look like today was going to be when we're going to vote," Rep. Phil Roe, R-Tenn., told the Hill. Another politician chimed in, saying, "If I were a betting man, I'd say there won't be a vote today."

House Speaker Paul Ryan, the most staunch defender of the bill, delayed his news conference on health care Thursday — twice. The news came as several politicians announced they would not support the American Health Care Act, which cannot pass if all the Democrats and 22 GOP lawmakers decide against it, USA Today reported.

The Congressional Budget Office estimated earlier this month that the bill would reduce the deficit by $337 billion through 2026 but leave about 24 million more people uninsured than would be under the current law. A Quinnipiac University poll out Thursday revealed that only 17 percent of Americans liked the Republicans' proposal, according to TIME, but the GOP was undeterred.

"It’s time to move on from seven years of Obamacare’s broken promises and unyielding attacks on the middle class," Senate Majority Leader Mitch McConnell, R-Ky., said on the floor. "The status quo is not an option. So let’s work together to get this done."
