WASHINGTON — The pressure to end the second-longest federal government shutdown is gaining new urgency this week as millions of Americans face the prospect of losing food assistance, more federal workers miss their first full paycheck and recurring delays at airports snarl travel plans.

Meanwhile, Republicans sent a report on former President Joe Biden’s use of an autopen to the Justice Department, urging further investigation.

The building strain on lawmakers to end the shutdown was magnified by the nation’s largest federal employee union, which called on Congress to immediately pass a funding bill and ensure workers receive full pay. Everett Kelley, president of the American Federation of Government Employees, said the two political parties have made their point.

“It’s time to pass a clean continuing resolution and end this shutdown today. No half measures, and no gamesmanship,” said Kelley, whose union carries considerable political weight with Democratic lawmakers.

Still, Democratic senators, including those representing states with many federal workers, did not appear ready to back down. Virginia Sen. Tim Kaine said he was insisting on commitments from the White House to prevent the administration from mass firing more workers. Democrats also want Congress to extend subsidies for health plans under the Affordable Care Act.

“We’ve got to get a deal with Donald Trump,” Kaine said.

“This week, more than any other week, the consequences become impossible to ignore,” said Rep. Lisa McClain, chair of the House Republican Conference.

The nation’s 1.3 million active-duty service members are at risk of missing a paycheck on Friday.

Earlier this month, the Trump administration ensured they were paid by shifting $8 billion from military research and development funds to make payroll. But it is unclear if the Trump administration is willing — or able — to shift money again.

Larger still, the Trump administration says funding will run out Friday for the food assistance program that is relied upon by 42 million Americans to supplement their grocery bills. The administration has rejected the use of more than $5 billion in contingency funds to keep benefits flowing into November. And it says states won’t be reimbursed if they temporarily cover the cost of benefits next month.

The Department of Agriculture says the contingency fund is intended to help respond to emergencies such as natural disasters. Democrats say the decision concerning the Supplemental Nutrition Assistance Program, known as SNAP, goes against the department’s previous guidance concerning its operations during a shutdown.

Senate Democratic leader Chuck Schumer of New York said the administration made an intentional choice not to the fund SNAP in November, calling it an “act of cruelty.”

At the Capitol, congressional leaders mostly highlighted the challenges many Americans are facing as a result of the shutdown. But there was no movement toward negotiations as they attempted to lay blame on the other side of the political aisle.

“Now government workers and every other American affected by this shutdown have become nothing more than pawns in the Democrats’ political games,” said Senate Majority Leader John Thune, R-S.D.

The House passed a short-term continuing resolution on Sept. 19 to keep federal agencies funded. Speaker Mike Johnson, R-La., has kept the House out of legislative session ever since, saying the solution is for Democrats to simply accept that bill.

But the Senate has consistently fallen short of the 60 votes needed to advance that spending measure. Democrats insist that any bill to fund the government also address health care costs, namely the soaring health insurance premiums that millions of Americans will face next year under plans offered through the Affordable Care Act marketplace.

Biden autopen report

House Republicans on Tuesday unveiled their long-promised report on former President Joe Biden’s use of the autopen, delivering a blistering critique of his time in office and inner circle that largely repeats public information while making sweeping accusations about the workings of his White House.

The GOP report does not include any concrete evidence that aides conspired to enact policies without Biden’s knowledge or that the president was unaware of laws, pardons or executive orders signed in his name. But Republicans said their findings cast doubt on all of the Democrat’s actions in office.

They sent a letter to Attorney General Pam Bondi urging a full investigation. Republican President Donald Trump ordered a similar inquiry earlier this year.

At its core, the report advances contested statements that Biden’s mental state declined to a degree that allowed White House officials to enact policies without his knowledge. It focuses heavily on the pardons he granted in office, including to his son, Hunter Biden, based on depositions with close Biden aides.

“The cost of the scheme to hide the fallout of President Biden’s diminished physical and mental acuity was great but will likely never be fully calculated,” the report reads. “The cover-up put American national security at risk and the nation’s trust in its leaders in jeopardy.”

Biden has denied he was unaware of his administration’s actions, calling such claims “ridiculous and false.” Democrats on the House Oversight committee denounced the probe as a distraction and a waste of time.

Johnson touted the 100-page report at a news conference and said the findings could have “major implications” for the legality of Biden’s actions as president, including pardons.

“The president was checked out of his job for quite some time, and everybody knows it,” Johnson said.

The report on Biden was largely compiled over several months before the shutdown began. Based on interviews with more than a dozen members of Biden’s inner circle, the report offers few new revelations.

It includes repeated references to polls of Biden’s approval rating and perceptions of his public gaffes and apparent aging, much of it publicly known.

It alleges a “cover-up of the president’s cognitive decline” orchestrated by Biden’s inner circle and takes particular aim at Biden’s doctor, Kevin O’Connor, who invoked his Fifth Amendment right against testifying. Republicans also singled out senior aides Anthony Bernal and Annie Tomasini, who similarly pleaded the Fifth.

All three “should face further scrutiny” from the Justice Department, Republicans said.

Republicans also sent a letter to the D.C. Board of Medicine urging that O’Connor face “discipline, sanction or revocation of his medical license” and “be barred from the practice of medicine in the District of Columbia.”

The report does not include full transcripts of the multiple hours of recorded testimony witnesses delivered before the committee. It repeatedly scolds Biden officials and Democratic allies for defending Biden’s mental state.

“The inner-most circle, or cocoon, of the White House senior staff organized one of the largest scandals in American history — hiding a cognitively failing president and refusing any means of confirmation of such demise,” the report says.
