'Greatest threat': Former top Kamala Harris aide reveals which Trump VP pick could sink her candidacy

Vice President Harris’ former communications director recently said there is one Republican who would be the "greatest threat" to her vice presidency if chosen as former President Trump’s 2024 running mate.

Ashley Etienne, who served as Harris’ communications director in 2021, told CNN on Friday that she believes Ohio Sen. JD Vance, R-Ohio, is an "incredible debater" and could present a challenge to Harris in the upcoming election.

"I think JD Vance would pose the greatest threat [to] Kamala Harris, in some respects. I mean he's an incredible debater," Etienne told CNN. "I think he has this quality that makes him seem palpable to that one to two percent that actually might vote or that is undecided, that will actually pay attention to the debates because most people don't pay attention to the debates."

Etienne, who also served as deputy assistant to President Biden after his 2020 victory, said Vance is "super smart," "quick-witted" and could pose a threat to Harris on the debate stage.

"I think he's just got a quality about him where he's super smart and sharp and quick-witted. I just think it's going to be a challenge to see the two of them face-to-face. I mean, maybe it's just me, but I think he's going to be the greatest threat," she said.

The comment comes as Harris’ disapproval rating remains high with 55% of registered voters having an unfavorable opinion of the vice president, according to a Fox News national survey from May.

Vance is on Trump's short list for vice president along with several other top Republican contenders.
