video of the incident:Joe Biden told a CBS reporter to "calm down" after he asked the former vice president why he had attacked Sen. Bernie Sanders (I-Vt.), a top rival of Biden's for the Democratic presidential nomination.
"Yesterday, you said you accepted Bernie's apology, now you're attacking him," said Ed O'Keefe, the veteran reporter covering the 2020 presidential campaign for the network. "Why are you doing that? Why wasn't his apology enough, Mr. Vice President? Why attack Sanders?"
After the last question, Biden, who had been ready to leave the press area, turned back to O'Keefe with a wide-eyed expression and walked back toward him.
"Why, why, why, why, why, why, why?" Biden said, waving his hands toward O'Keefe and bending toward him slightly.
"You're getting nervous, man. Calm down, it's OK!" Biden said, putting his hands gently on O'Keefe's shoulder.
"He apologized for saying I was corrupt, he didn't say anything about whether or not I was telling the truth about Social Security," Biden then states, as O'Keefe recorded the conversation.
Biden proceeded to give the reporter a soft tap with his fist before leaving the area.
