Sen. Cory Booker (D-NJ) officially broke the record Tuesday night for the longest floor speech in the history of the United States Senate.
For a continuous day, the senator held the floor to condemn President Donald Trump's dismantling of the federal government via tech billionaire Elon Musk and his Department of Government Efficiency task force.
"It should not be possible in America for one single man — even an elected president — to stop funds which Congress has already allocated," said Booker near the beginning of the speech on Monday evening.

Under Senate rules, an individual senator can hold the floor indefinitely but must speak continuously through that entire time without sitting down, taking a bathroom break, or otherwise leaving the floor, and can only pause to yield to other senators for questions.
Senate Majority Chuck Schumer interrupted Booker on Tuesday to let Booker know he'd broken the record.
"Do you know how proud America is of you?" asked Schumer, to applause.
Prior to Booker's marathon speech, the longest floor speech in Senate history was delivered by Sen. Strom Thurmond (D-SC) in 1957 to protest the passage of an early version of the Civil Rights Act. An ardent segregationist, Thurmond changed his affiliation to the Republican Party as Democrats decisively passed an even more expansive civil rights bill in 1964 and continued to serve in the Senate until he died in 2003.
More recently, Sen. Ted Cruz (R-TX) gave a marathon speech in 2013 to push a federal government shutdown to stop enactment of the Affordable Care Act, during which he famously padded out his speaking time by reading from Dr. Seuss' "Green Eggs and Ham."
