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.

The president-elect announced Wednesday that he was nominating Kathleen Hicks as the deputy secretary of defense and Colin Kahl as the under secretary of defense for policy.

“These respected, accomplished civilian leaders will help lead the Department of Defense with integrity and resolve, safeguard the lives and interests of the American people, and ensure that we fulfill our most sacred obligation: to equip and protect those who serve our country, and to care for them and their families both during and after their service,” Biden said in a statement. “Dr. Kath Hicks and Dr. Colin Kahl have the broad experience and crisis-tested judgment necessary to help tackle the litany of challenges we face today, and all those we may confront tomorrow.”

Hicks currently leads the Biden-Harris Transition’s Defense Agency Review Team and is the senior vice president and director of the International Security Program at the Center for Strategic and International Studies. During the Obama-Biden Administration, she served as deputy under secretary of defense for strategy, plans, and forces and was confirmed by the Senate to serve as principal deputy under secretary of defense for policy.

Kahl is currently a co-director of the Center for International Security and Cooperation, a Steven C. Házy Senior Fellow at the Freeman Spogli Institute for International Studies and a professor of political science at Stanford University.
