CNN anchor Don Lemon's visible outrage over a hung jury in the Michael Dunn trial caught the attention Sunday of Fox News anchor Gregg Jarrett, who lobbed a series of personal attacks over Twitter.

Later, Lemon replied on Twitter "wow, someone is suffering from a bad case of the Michael Dunns. Guess my tv's too loud... Mind ur business old man."

... to which Jarrett responded around 6 p.m. Sunday.

Jarrett has not been active on Twitter for about four months before these comments.
