Republicans voted against a key procedural vote to proceed with debate on the $1.2 trillion infrastructure bill in the Senate, as lead GOP negotiator Rob Portman told they would CNBC on Wednesday morning.
Portman's prediction was realized when the vote failed 49-51 in the Senate with all Republicans lined up against the measure.
Senate Majority Leader Chuck Schumer, D-N.Y., changed his vote to "no" in order to be able to bring the vote up again.
"We're just not ready," the Ohio senator had warned Wednesday morning in a "Squawk Box" interview.
"The bill is still being negotiated," Portman said, adding that Republicans have warned for days that "there's no way we can pull this thing together" in time for the Wednesday vote set by Schumer.
"So we're going to vote no," Portman said. "We just want time to get it right."
He added that Republicans would be able to support the vote if it is pushed to Monday.
On the Senate floor Wednesday morning, Schumer once again rejected Republican calls to delay the vote.
"I've been very clear about what this vote is," Schumer said, calling it "the first step in the legislative process."
"This vote is not a deadline to have every final detail worked out," he said.
Schumer and other Democratic leaders, with the backing of President Joe Biden, seek to advance the bipartisan infrastructure bill in tandem with a $3.5 trillion budget resolution that is likely to get no Republican support.
The bipartisan plan, which would fund a nationwide update of physical infrastructure systems such as bridges and waterways, would include $579 billion in new spending above a congressional baseline and cost $1.2 trillion over eight years.
The budget resolution, meanwhile, would pour federal money into addressing an array of issues, including climate change and health care.
Facing a tough legislative calendar to pull off this "two-track" feat, Schumer has ratcheted up pressure on the group of senators negotiating the infrastructure bill to finish up with the text of the legislation.
Schumer on Monday evening pushed the legislative process forward — even though the bill has yet to be written — by filing a motion to proceed with a shell bill that he can later swap the infrastructure text into.
To invoke cloture and trigger hours of debate in the Senate, Schumer needs the support of 60 senators in a chamber that is divided 50-50 between Republicans and Democrats.
Schumer said Tuesday that if the vote fails, Republicans would "be denying the Senate an opportunity to consider the bipartisan amendment."
"In order to finish the bill, we first need to agree to start," he said.
On Wednesday morning, Senate Minority Leader Mitch McConnell, R-Ky., said that Schumer "appears to be intent on calling a vote he knows will fail."
"Around here, we typically write the bills before we vote on them. That's the custom," McConnell said on the Senate floor.
