The U.S. Senate has begun the process of reopening the government after the longest shutdown in history.

The vote to begin the process came after Senate Republicans brokered a deal with eight moderate Senate Democrats. The deal includes a provision that would bring a vote for more Medicare funding, but does not guarantee passage. While there are enough votes for passage, many Democrats are still not on board and could delay a final vote.

“Democrats demanded that we find a way to fix this crisis and quickly,” Senate Minority Leader Chuck Schumer (D-NY) said. “But Republicans have refused to move an inch, so I cannot support the Republican bill that is on the floor.”

Republicans remain optimistic that the deal will move out of the Senate before the end of the week, with Speaker of the House Mike Johnson preparing for a House vote as soon as the Senate passes the bill.

“I’m stating the obvious to all my colleagues,” Johnson said. “Republicans and Democrats in the House, you need to begin right now returning to the Hill. We have to do this as quickly as possible.”

Once the deal passes both the Senate and the House, the funding bill will be sent to President Trump, who is expected to sign it.
