New Jersey senator Cory Booker broke a nearly 70-year-old record Tuesday with a marathon speech on the Senate floor criticizing Trump administration policies, which he spent days preparing for.

“I didn’t know how long I could go. I’m so grateful I lasted for 25 hours [and four minutes],” Booker told reporters after leaving the floor.

Booker ignored a question about whether he wore a catheter or a diaper, or had any assistance to avoid using the bathroom. Instead he described his pre-speech regimen, which including starting to fast on Friday, avoiding fluids after Sunday night and reading more than 1,100 pages of research.

“I fasted for days into it. I stopped drinking water a long time ago. I think that had good and bad benefits. I definitely started cramping up from lack of water,” he said. “So there’s just a lot of tactics I was using to try to make sure that I could stand for that long.

“I really spent time dehydrating myself beforehand so I did not have to go to the bathroom,” he said.

During the speech, he occasionally sipped from glasses of water on his desk — which he hovered around throughout — and did not sit down.

As the hours ticked away, Booker drew millions of views on social media.

The speech broke a previous record set by Sen. Strom Thurmond, who filibustered the Civil Rights Act of 1957 for 24 hours and 18 minutes.

“To be candid, Strom Thurmond’s record always kind of just really irked me — that he would be the longest speech, that the longest speech on our great Senate floor was someone who was trying to stop people like me from being in the Senate,” Booker told Rachel Maddow later Tuesday.

“So to surpass that was something I didn’t know if we could do, but it was something that was really, once we got closer, became more and more important to me.”
