Trump cut it and Biden restored it in 2021. I think there was a short stoppage of funding after 10/7 that was restored again this past April (ETA: This last part is wrong, it is still on pause but Biden has said he wants to fund again. He can't unless Congress allows and it can't occur until next year according to Politico. I mixed up a charity called US UNRWA extending its funding thinking it was actually the US)

On Biden resuming after Trump had cut before 10/7:
Two-thirds will go to the UN agency for Palestinian refugees, which Donald Trump stopped funding.
