Pelosi said she may not hold vote on infrastructure bill on Monday as planned if it doesn't have the votes

• House Speaker Nancy Pelosi said Sunday she may not hold a vote on the infrastructure bill on Monday.
• Pelosi said she wouldn't hold a vote on the legislation unless she was sure it would pass.
• "I'm never bringing a bill to the floor that doesn't have the votes," she said.

House Speaker Nancy Pelosi on Sunday said she wasn't sure if she'd hold a vote for the $1.2 trillion bipartisan infrastructure bill on Monday as previously planned because it may not have enough votes to pass.

"Let me just say we're going to pass the bill this week," said Pelosi, a Democrat from California, during an appearance on ABC's "This Week." "I promised that we would bring the bill to the floor."

But Pelosi said she wasn't in favor of bringing the bill to a vote on an "arbitrary date" if she did not believe there was enough support to pass it. The September 27 date was set after the bill easily passed the Senate in August.

"I'm never bringing a bill to the floor that doesn't have the votes," she said Sunday. "Remember when the Republicans said they were going to overturn the Affordable Care Act on the anniversary of the Affordable Care Act? I knew right then and there they were doomed."

Republicans in 2017 failed to pass a measure that would've repealed the Affordable Care Act, which passed in March 2o10. The late GOP Sen. John McCain and two other Republican senators - Susan Collins of Maine and Lisa Murkowski of Alaska - voted against the bill, resulting in a 49-51 vote.

"You can't choose the date," Pelosi said. "You have to go when you have the votes in a reasonable time. And we will."

Pelosi previously told reporters the bill would receive a vote on Monday, though progressive lawmakers have said the bill will not have the votes to make it through.

"It cannot pass," Rep. Pramila Jayapal, a Democrat from Washington and the head of the Congressional Progressive Caucus, said Friday, according to The Hill. "I don't bluff, I don't grandstand. We just don't have the votes for it."

While these Democrats don't oppose the nature of the bipartisan infrastructure bill, some lawmakers say they will refuse to put their support behind it until the House takes up President Joe Biden's $3.5 trillion social spending package, which includes investments in several sectors, including healthcare, childcare, and climate change.

Democrats plan to pass the social spending packing in the Senate through a process known as reconciliation, which would allow them to avoid the use of the filibuster by Republicans.

"It's not going to give us any comfort to pass a bill that then the Senate [defeats]," Jayapal said, per The Hill. "That doesn't satisfy our requirements."

"It can only come to the floor once everyone's agreed and once the Senate has voted on it," she added.

But every Democrat in the Senate needs to vote in favor of the bill for it to pass, putting the focus on moderate Democrat Sens. Joe Manchin of West Virginian and Kyrsten Sinema of Arizona.

"It's an eventful week," Pelosi said Sunday. "We have to make sure we keep the government open and we will."
