Former Secret Service Agent Gary Byrne said that after an explosive argument in 1995 between the first couple that left a White House vase smashed and President Bill Clinton with a black eye, officers became concerned for the president's personal safety.
Byrne said on Hannity that the agents discussed what they should do in the event of a domestic dispute.
The author of the shocking tell-all Crisis of Character said that agents would give each other a "heads up" if the president was with a mistress.
"We were concerned. I mean, what if she did catch the president in a compromising situation?"
He said there was a plan in place to warn the president before that could happen.
