WASHINGTON – It's been more than 20 hours. Sen. Cory Booker has not sat down, or even wandered far from his desk on the Senate floor, where he has been delivering a marathon speech railing against President Donald Trump and his administration's sweeping policy changes.

A member of the U.S. Senate took the floor at 7:00 p.m. on Monday evening — and he doesn’t plan on leaving it any time soon. In a text message to TPM, Sen. Cory Booker (D-NJ) said he was about to begin speaking for as long as he could stand.
