The Senate is planning to debate and vote on the Safeguard American Voter Eligibility Act, called the SAVE America Act, through this weekend as Senate conservatives warn that a failure to make significant progress on Trump’s No. 1 legislative priority could result in Republican voters sitting out the election in November.

The Senate is expected to vote Saturday on an amendment sponsored by Sen. Tommy Tuberville (R-Ala.), a staunch Trump ally, to bar transgender athletes from participating in women’s sports.

Then the Senate will pivot to vote Sunday on a motion to advance the nomination of Sen. Markwayne Mullin (R-Okla.) to serve as secretary of the Department of Homeland Security, which would set up a final confirmation vote for Mullin on Monday.
