Summary

Sen. Cory Booker broke the all-time Senate filibuster record Tuesday with a 25-hour, 4-minute speech opposing proposed Social Security cuts by Elon Musk.

Booker criticized the broader Trump agenda and warned of threats to democracy.

Sen. Ted Cruz said he was thinking about triggering the alarm on the Senate floor to block the New Jersey Democrat from surpassing his marathon speech mark, then joked on X and posted a Homer Simpson meme.

Booker began speaking Monday at 7 p.m. and remained standing throughout, aided by Democratic colleagues who questioned him to allow brief breaks.
