Pennsylvania Gov. Josh Shapiro (D) said Vice President Kamala Harris will “have to answer to how” she never publicly voiced concerns about her former boss, Joe Biden’s, fitness to serve as president, even though she had a front-row seat in his administration. (Watch video below.)

In an interview with Stephen A. Smith released on Thursday, Shapiro was asked to weigh in on Harris’ recent assessment that she was wrong to hold back from advising Biden against pursuing another presidential run.

“Look, I haven’t read the former vice president’s book,” Shapiro said of Harris. “She’s going to have to answer to how she was in the room, and yet never said anything publicly.”

Shapiro stressed that he didn’t have the same access to Biden as Harris, but still engaged with him and his team regarding their campaign’s performance in Pennsylvania, a swing state.

“I think, Stephen, you understand, if you can’t win Pennsylvania, it’s pretty darn hard to win the national election,” Shapiro said. “And I was very vocal with him privately, and extremely vocal with his staff about my concerns about his fitness to be able to run for another term. I was direct with them.”
