According to CNN, Sen. Cory Booker has broken the record for the longest floor speech in Senate history, surpassing the 24-hour, 18-minute mark set by Strom Thurmond in 1957.

Thurmond’s speech famously opposed the Civil Rights Act, while Booker’s protest targets policies under President Donald Trump.

Beginning at 7 p.m. Monday, Booker vowed to speak as long as physically possible, voicing concern over Medicaid cuts, attacks on democratic norms, and billionaire influence in government.

Throughout the night, fellow Democrats, including Chuck Schumer and Chris Murphy, supported him.

Though not a filibuster, Booker’s speech delayed Senate proceedings and served as a symbolic stand, calling the current political moment a “crisis” and invoking John Lewis for moral inspiration.
