The fiery exchange unfolded as the US president welcomed 16-year-old lifeguard Ryder Williams to the White House after he rescued the youngster from powerful waves off the California coast last month.
The boy, Nathanial Rai, was also sitting in the Oval Office alongside Williams and his family. Trump appeared to drag Nathanial into the confrontation, turning to the youngster and asking whether he also found the reporter disrespectful.
"You're very disrespectful in front of this young man, okay? Don't you find her disrespectful? He understands," Trump said before repeatedly ordering CNN reporter Kristen Holmes to stop speaking.
