Utah GOP Sen. Mike Lee implored his colleagues Wednesday to help him identify his fellow conservative senators who do not support the Safeguard American Voter Eligibility (SAVE) America Act.

The comment comes after Senate Majority Leader John Thune warned earlier Wednesday that the Republican conference in the upper chamber was not unified on the prospect of using the talking filibuster to pass the SAVE Act.

"Not unified on using the talking filibuster to pass the SAVE America Act?" Lee posted on X. "It’s time to *get* unified. We can’t afford the consequences of inaction. GOP senators who aren’t supportive should identify themselves & make their case—rather than silently stalling." 

The SAVE America Act requires individuals to present proof of citizenship to register to vote and requires those Americans to show ID when voting. The legislation has already passed the House but stalled in the Senate.

The plea also comes after Lee said earlier this month that 49 senators are now sponsoring the legislation, and Maine GOP Sen. Susan Collins supports the bill.
