Senate Democrats will use Thursday's anniversary of the Jan. 6 attack on the U.S. Capitol to propel their efforts to pass sweeping voting rights legislation. Driving the news: In a letter to colleagues Monday morning, Senate Majority Leader Chuck Schumer (D-N.Y.) said the Senate will debate and vote on changing Senate rules if Republicans block a vote on the Freedom to Vote Act backed by Sen. Joe Manchin (D-W.Va.). Schumer promised a vote on Senate reforms by Martin Luther King Jr. Day on Jan. 17.
