Sen. Cory Booker's Senate floor speech in April lasted more than 25 hours, making it longer than Jeff Merkley's 22-hour speech.
Notes on verification
Confirmed by multiple independent, high-quality news sources (CBS, NBC, ABC, NPR) and Booker's own Senate office record, plus Wikipedia. Both speech durations and the comparison are consistently corroborated.
