The Senate is back in session for the first time in months.
The Republican-controlled chamber is set to vote on a resolution to reopen funding for the government at noon EST.
The GOP-led chamber passed a spending bill that would reopen the federal government for the next two weeks, allowing Congress to reopen for a week-long Easter recess.
The government was shut down again Friday for several weeks for the shutdown over an issue involving the Keystone XL pipeline.
The funding bill passed on Thursday would have extended the shutdown until Sept. 30, if not longer.
It is unclear how much longer the shutdown will last.
