More than 140 mayors have asked the US Senate to act to pass two pieces of sweeping voting rights legislation. Both bills have been stalled for months because no Republicans support them.

Senate Democrats are expected to make a new push in the coming days to do away with the filibuster, a senate rule that requires a 60-vote supermajority to advance legislation. Republicans used the rule to block the voting rights bills several times last year.

One bill, the Freedom to Vote Act, would set sweeping national guarantees for voting access, including 15 days of early voting, as well as guaranteed automatic and same-day voter registration. The second measure, the John Lewis Voting Rights Advancement Act, would restore a critical provision of the Voting Rights Act that gives the federal government more oversight over US elections.
