WASHINGTON — Compromising with moderates, House Democratic leaders will try again Tuesday to muscle President Joe Biden’s multitrillion-dollar budget blueprint over a key hurdle, hoping to end a standoff that risked upending their domestic infrastructure agenda.

Tensions flared overnight as a band of moderate Democrats including Rep. Jared Golden of Maine’s 2nd District threatened to withhold their votes for the $3.5 trillion plan. They were demanding the House first approve a nearly $1 trillion bipartisan package of road, power grid, broadband and other public works projects that’s already passed the Senate.

Early Tuesday, House leaders surveyed support for a potential compromise. It would set a Sept. 27 date to consider the bipartisan package, giving moderates the assurance they want, according to a Democratic aide granted anonymity to discuss ongoing negotiations.

The potential compromise attempts to meet the concerns of moderates that the bipartisan package won’t be left on the sidelines, but also stays in line with House Speaker Nancy Pelosi’s insistence that the two bills move together as a more complete package of Biden’s priorities. Pelosi has set a goal of passing both by Oct. 1.

“We’re close to landing the plane,” Pelosi told lawmakers Tuesday, according to a Democratic aide granted anonymity to discuss the closed-door caucus meeting.

The new strategy comes after a turbulent late night at the Capitol and signals the power even a handful of voices can have in setting policy and agenda in the narrowly divided chamber, where Pelosi has few votes to spare. What was supposed to be a quick session as lawmakers returned to work for a few days in August devolved into a dramatic display of differences between moderates and progressive lawmakers over the best way to tackle Biden’s agenda.

On Tuesday, she apologized to lawmakers for the delays, according to the aide, but chalked them up as “just part of the legislative process.”

With Republicans fully opposed to the president’s big plans, the Democratic leaders were trying to engineer a way out of a potentially devastating standoff between the party’s moderate and progressive wings that risks Biden’s agenda.

Inserting his own wedge into the politics of the situation, Senate Minority Leader Mitch McConnell, R-Kentucky, said Tuesday on Fox News that he was rooting for the House moderates. He had supported the nearly $1 trillion bill that passed the Senate earlier this month, but is planning to lead Senate Republicans lockstep against Biden’s infrastructure agenda.

“I wish the moderates in the House success,” McConnell said.

Despite hours of negotiations at the Capitol, the House chamber came to a standstill and plans were thrown into flux late Monday, as leaders and lawmakers huddled privately to broker an agreement.

Pelosi’s leadership sought to sidestep the issue by persuading lawmakers to take a procedural vote to simply start the process and save the policy fight for the months ahead, when they will be crafting and debating details within the full $3.5 trillion budget proposal.

But it soon became clear that moderates were not on board and a series of other private sessions were convened with them for further discussion, including in Pelosi’s office. What had been a night of scheduled votes came to an unexpected standstill that dragged to midnight.

Challenging their party’s most powerful leaders, nine moderate Democrats including Golden signed onto a letter late last week raising their objections to pushing ahead with Biden’s broader infrastructure proposal without first considering the smaller public works plan that has already passed the Senate. Other moderates raised similar concerns in recent days.

In the narrowly divided House, every vote matters and a few dissenters could conceivably end the Democratic majority’s hopes for passing any proposal.

The budget measure is at the heart of Biden’s “Build Back Better” vision for helping families and combating climate change and is progressives’ top priority, all of it largely financed with tax increases on the rich and big business. House committees are already fast at work drafting legislation to fill in the details of the $3.5 trillion package for consideration later this fall, in what could be another showdown between moderates and progressives.

Progressives signaled early on they wanted the Biden budget priorities first before they agree to the smaller package, worried it would be an insufficient down payment on his goals. But the moderates want the opposite, insisting Congress quickly send the smaller, bipartisan infrastructure measure to Biden so he can sign it before the political winds shift.

“The House can’t afford to wait months or do anything to risk passing” the infrastructure bill, Rep. Josh Gottheimer, D-N.J., a leader of the moderates, said last week.
