"I got a boo," he said Tuesday on radio show The Breakfast Club. "Before I declared for president, I’m dating someone that’s really special to me,"
Booker, 49, laughed off questions about whether his status as a bachelor could affect his White House chances.
"First of all, there’s two more years until I might fulfill this duty, so give me some time," he said. "My girlfriend might listen to this."
He also added, "I think that if Donald Trump can get elected president at this point with the personal life that he has, then anybody can."
