WASHINGTON (AP) — Senate Republicans will test the popularity of Department of Government Efficiency spending cuts this week by aiming to pass President Donald Trump’s request to claw back $9.4 billion in public media and foreign aid spending.

Senate Democrats are trying to kill the measure but need a few Republicans uncomfortable with the president’s effort to join them.

Trump’s Republican administration is employing a rarely used tool that allows the president to transmit a request to cancel previously approved funding authority. The request triggers a 45-day clock under which the funds are frozen. If Congress fails to act within that period, then the spending stands. That clock expires Friday.

The House has already approved Trump’s request on a mostly party line 214-212 vote. The Senate has little time to spare to beat the deadline for the president’s signature. Another House vote will be needed if senators amend the legislation, adding more uncertainty to the outcome.

Trump has asked lawmakers to rescind nearly $1.1 billion from the Corporation for Public Broadcasting, which represents the full amount it’s due to receive during the next two budget years.

The White House says the public media system is politically biased and an unnecessary expense.

The corporation distributes more than two-thirds of the money to more than 1,500 locally operated public television and radio stations, with much of the remainder assigned to National Public Radio and the Public Broadcasting System to support national programming.

The potential fallout from the cuts for local pubic media stations has generated concerns on both sides of the political aisle.

Sen. Mike Rounds, R-S.D., said he’s worried about how the rescissions will hit radio stations that broadcast to Native Americans in his state. He said the vast majority of their funding comes from the federal government.

“They’re not political in nature,” Rounds said of the stations. “It’s the only way of really communicating in the very rural areas of our state, and a lot of other states as well.”

Sen. Lisa Murkowski, R-Ala., said that for the tribal radio stations in her state, “almost to a number, they’re saying that they will go under if public broadcasting funds are no longer available to them.”

To justify the spending cuts, the Trump administration and Republican lawmakers have cited certain activities they disagree with to portray a wide range of a program’s funding as wasteful.

In recent testimony, Office of Management and Budget Director Russ Vought criticized programming aimed at fostering diversity, equity, and inclusion. He said NPR aired a 2022 program entitled “What ‘Queer Ducks’ can teach teenagers about sexuality in the animal kingdom.” He also cited a special town hall that CNN held in 2020 with “Sesame Street” about combatting racism.

As part of the package, Trump has asked lawmakers to rescind about $8.3 billion in foreign aid programs that aim to fight famine and disease and promote global stability.

Among the targets:

— $900 million to combat HIV/AIDS, malaria and other diseases and strengthen detections systems to prevent wider epidemics.

— $800 million for a program that provides emergency shelter, water and sanitation and family reunification for those forced to flee their own country.

— $4.15 billion for two programs designed to boost the economies and democratic institutions in developing and strategically important countries.

— $496 million to provide humanitarian assistance such as food, water and health care for countries hit by natural disasters and conflicts.

Some of the health cuts are aimed at a program known as PEPFAR, which President George W. Bush, a Republican, began to combat HIV/AIDS in developing countries. The program is credited with saving 26 million lives and has broad bipartisan support.
