Gabbard and Harris reignited a feud initially sparked during the September Democratic debate, when Gabbard took aim at Harris over her controversial record on criminal justice.
In the November debate, Harris attacked Gabbard for her frequent, pointed criticism of the Democratic party's foreign policy doctrine, which Gabbard casts as promoting dangerous interventionism.
"It's unfortunate that we have someone on this stage who during the Obama administration spent four years full-time on Fox News criticizing President Obama," Harris said.
In turn, Gabbard accused Harris of "trafficking in lies, smears, and innuendos because she cannot challenge the substance of the argument I'm making."
