Pennsylvania Gov. Josh Shapiro said Kamala Harris “is going to have to answer” for not publicly raising concerns about former President Joe Biden’s fitness to do the job before the 2024 presidential election, telling Stephen A. Smith in an interview released Thursday that her silence needs explaining.

“I haven’t read the former vice president’s book,” Shapiro told Smith on his SiriusXM show.

He said Harris was going to have to answer for “how she was in the room and yet never said anything publicly.”

Shapiro, who was among a shortlist of candidates for VP under Harris before she picked Minnesota Gov. Tim Walz, added that he voiced his own doubts privately to Biden’s team.

“I was direct with them,” the Democratic governor told Smith.

“I told them my concerns.”

Shapiro, whose named has been mentioned as a possible presidential candidate in 2028, framed his critique around the battleground stakes.

“If you can’t win Pennsylvania, it’s pretty darn hard to win the national election,” he said.

The governor’s remarks followed fresh excerpts from Harris’s forthcoming memoir, “107 Days,” which depict Shapiro as unusually focused on the trappings of the vice presidency during vetting — including asking how many bedrooms are in the Naval Observatory residence and whether the Smithsonian would lend Pennsylvania art to display.

Harris also wrote that she considered him likely to want to be “in the room for every decision.”

A Shapiro spokesperson, Manuel Bonder, called those claims “simply ridiculous,” saying the governor was focused on defeating the eventual winner, President Donald Trump, and campaigned hard for the ticket.

Harris’s book revisits the period after Biden’s faltering debate and the weeks of internal debate over his future.

She writes she was “in the worst position to make the case that he should drop out,” fearing any push would be seen as “poisonous disloyalty.”

“In retrospect, I think it was recklessness. The stakes were simply too high,” Harris writes in an excerpt published by The Atlantic.

The memoir’s first chapter opens on July 21, 2024 — the day Biden told her he would exit the race. The then-president withdrew weeks after unrelenting pressure in the wake of a disastrous debate performance against Trump.

Harris then mounted a 107-day campaign against Trump, the duration that gives the book its title, according to the publisher’s listing.

She details the vice-presidential search, writing that Pete Buttigieg, who is gay, was her “first choice” for running mate but that the pairing was “too big of a risk” due to his sexual orientation.

“We were already asking a lot of America: to accept a woman, a Black woman, a Black woman married to a Jewish man,” Harris wrote in her book.

“Part of me wanted to say, ‘Screw it, let’s just do it.’ But knowing what was at stake, it was too big of a risk.”

Buttigieg, responding to Harris’s rationale about the risks of a Harris–Buttigieg ticket, said he was “surprised” by the passage and argued voters judge leaders by what they’ll do for their lives, not “categories.”

Harris’s book, which was published by Simon & Schuster, goes on sale Tuesday.

The Post has sought comment from Harris and Biden.
