Billy Bush, a host on the “Today” show who has received stinging criticism for his role in a video with Donald J. Trump, has been suspended by NBC.

The NBC executive in charge of “Today,” Noah Oppenheim, wrote in a memo to his staff members on Sunday that “we’ve all been deeply troubled by the revelations of the past 48 hours.”

“Let me be clear — there is simply no excuse for Billy’s language and behavior on that tape,” he said. “NBC has decided to suspend Billy, pending further review of this matter.”
