WASHINGTON (AP) — The Senate is working overnight to pass legislation that would fund President Donald Trump’s immigration enforcement agencies as Democrats and some Republicans have tried to add language to permanently block Trump from creating a $1.776 billion settlement fund.

Earlier in the day, Republicans turned back a Democratic effort to block the fund, which would compensate the president’s allies who say they have been politically persecuted. But there were potentially more amendments to come overnight as Republican Sen. Bill Cassidy of Louisiana has said he will try again to block the settlement.
