Former President Barack Obama used a red button in the Oval Office to order tea, according to Richard Branson’s new book.

“As we stood up to leave I noticed the red buttons on his desk,” Branson wrote in his new autobiography, “Finding My Virginity,” of the Resolute Desk. “Obama saw me looking at them. He said, ‘They used to be there for emergencies, but now I use them for ordering tea for my guests.'”
