WASHINGTON (AP) — The Republican-led Senate is moving forward with legislation to fund immigration enforcement agencies after forcing the White House to drop its settlement fund for political allies and stripping a separate proposal for White House security from the bill.

The Senate voted 53-46 on Wednesday to begin debate on the roughly $70 billion bill to fund U.S. Immigration and Customs Enforcement and the Border Patrol. The legislation was delayed for weeks as Republican senators navigated the various obstacles to passage created by President Donald Trump and the White House, but they are now moving quickly to pass it after paring it back to its original form.

“Right now, the goal is to get the base bill across the finish line,” said Senate Majority Leader John Thune, R-S.D.

Still, Republicans will need to find enough votes to beat back multiple amendments that Democrats — and potentially some Republicans — say they will offer. Republicans are using a process called budget reconciliation that enables them to pass the legislation without any Democratic votes, but they must first wade through a long series of amendment votes that could pose problems for the bill. That process could start as soon as Wednesday evening.

The primary threat during amendment votes is a series of expected Democratic proposals to permanently ban Trump’s $1.776 billion settlement fund, which his administration scrapped on Tuesday after fierce Republican pushback. While acting Attorney General Todd Blanche told Congress that “we are not moving forward with the fund, period,” Democrats say they want it written into the law.

“It is only a matter of time before Blanche and Trump go back on their word,” said Senate Minority Leader Chuck Schumer, D-N.Y.
