After days of opposition and hours before the federal government was going to shut down, Trump signed a $2.3 trillion bill into law Sunday night to avert a government shutdown and extend $900 billion in coronavirus pandemic relief -- but millions of American will be impacted by his delay.

Trump’s Sunday night signature came after two critical unemployment programs lapsed over the weekend, leaving roughly 14 million Americans who have relied on the income without a week of benefits during the holiday season. While the current bill shells out $600 direct payments for most Americans, Trump is breaking from his party by continuing his push to bring that amount to $2,000.

In a Sunday night statement announcing he had signed the bill, Trump -- who has sat on the sidelines of negotiations for months -- also called on Congress to make more revisions to cut down excess spending, saying "wasteful items need to be removed" from the bill and that he would send back a “redlined” version.

The move is forcing Senate Republicans, many who did not support more direct payments, to say whether they stand with Trump on increasing payments and revisiting the bill’s language or by their previous positions.

House Speaker Nancy Pelosi on Monday is bringing a vote on a stand-alone bill to increase economic impact payments to $2,000 to the House floor, and while it’s expected to pass the House, it’s unclear whether Senate Majority Leader Mitch McConnell will take up the measure in the Senate.

The president has no public events on his schedule as he continues his holiday from Mar-a-Lago, and threatens, via Twitter, a challenge to the counting of the Electoral College vote in Congress on Jan. 6.

Biden, meanwhile, is pressing forward with his transition with less than a month until his inauguration. The president-elect is slated to meet with members of his national security and foreign policy agency review teams on Monday and deliver afternoon remarks on their "findings and the key challenges his administration will inherit" from Wilmington, Delaware.

In her first meeting as interior secretary-designee, Deb Haaland hosted a virtual roundtable with tribal leaders on Monday morning, according to the Biden transition team.

Joined by incoming senior adviser to the president and director of the White House Office of Public Engagement Cedric Richmond and incoming director of the White House Office of Intergovernmental Affairs Julie Rodriguez, Haaland “reiterated President-elect Joe Biden’s promise to Tribal Nations and indigenous communities to fully honor America’s sacred trust and treaty obligations to Tribal Nations,” the transition said in a readout of the meeting.

“They also discussed how the incoming Biden-Harris Administration will work in coordination with tribal communities who bear disproportionate harm from long-running environmental injustices and are being adversely affected by the impacts of climate change on their homelands,” the readout continued.

Haaland addressed Biden’s ambitious climate policy during the meeting, discussing the incoming administrations plans to address the inequities of global warming and efforts to address climate change, treating it as an economic opportunity. She also pledged to ensure that the Interior Department engages in "early, frequent, and meaningful consultation" with tribal leaders on decisions that affect indigenous communities, according to the readout.

If the Senate confirms her as secretary of the interior, Haaland would be the first Native American to serve in a presidential Cabinet and would be the first Native person to oversee an agency that's played a major role historically in the forced relocation and oppression of Indigenous people.
