The Senate is working overnight into the early hours of Thursday morning as it weighs whether to claw back $9 billion in federal funds already congressionally approved for foreign aid and public broadcasting programs as a deadline to act on the White House priority looms.

GOP senators said they would remove $400 million in cuts to PEPFAR from the rescissions proposal, which targets foreign aid and public broadcasting, ahead of a Friday deadline.

The rescissions bill to claw back funding approved for foreign aid, NPR and PBS is a top Trump priority, but some Senate Republicans have raised concerns about the cuts.

Senate Republicans on Tuesday advanced President Donald Trump's request to cancel some $9 billion in previously approved spending, overcoming concerns about what the rescissions could mean for impoverished people around the globe and for public radio and television stations in their home states.
