A former FDNY commissioner who served during the 9/11 terror attacks shredded a local congressman who peddled outlandish conspiracy theories on an unearthed blog  – calling the Democrat “unfit” for office.

Former commissioner Tom Von Essen’s harsh words for US Rep. Jamaal Bowman came after it was revealed he made comments on a long-since deleted blog that entertained the possibility the 2001 terror attacks on the World Trade Center were an inside job.

“Jamaal Bowman and George Santos should be in business together,” Von Essen said, referring to the serial lying ex-congressman from Long Island who was booted from office last year.

“There are crazy people out there. There are people who said I planted explosives on the floors of the World Trade Center towers,” added Von Essen, who also served as the New York-NJ regional director of the Federal Emergency Management Agency during the COVID-19 outbreak.

“Bowman is definitely unfit to be in Congress. He’s definitely someone we don’t need,” Von Essen told The Post.

Bowman —  a member of the liberal House “Squad” that also includes Rep. Alexandria Ocasio-Cortez (D-NY) — kept a blog more than a decade ago that claimed WTC building No. 7 was destroyed in a controlled demolition and that hijacked Flight 93 and Flight 77 caused minimal damage and left behind little debris. The posts were unearthed by The Daily Beast.

The former Bronx middle school principal also claimed that Osama bin Laden, a Saudi native, was “blamed” for the attacks as an excuse to wage war in Afghanistan, when in fact the terror leader had openly taken credit for the massacre.

Investigators determined that WTC 7 buckled after debris from the Twin Towers started a fire, and hijackers steered Flight 77 into the Pentagon in Virginia, killing all 64 people on the plane and 125 in the building.

Bowman, who was elected to the House in 2020, also reportedly promoted the conspiracy theory movies “Loose Change” and “Zeitgeist” on the blog.

“Loose Change” asserted that the US carried out the 9/11 attacks and “Zeitgeist” promoted the suggestion that globalist bankers were behind the tragedy in a scheme to influence the US to go to war and take on more debt.

Von Essen also said Bowman admitting he pulled a fire alarm before a budget vote in a House office though there was no emergency was dangerous and showed poor judgement. The alarm temporarily delayed a vote to avert a government shutdown, but Bowman has denied he intended to disrupt the proceedings.

“It’s bad enough what he did as a citizen, Von Essen said. “He’s continued to make bad decisions.”

Other 9/11 health activists said Bowman has to go.

“Bowman disrespected thousands killed that day and continue to die. He has no place in Congress,” said 9/11 health advocate John Feal.

The Post reached out Bowman for comment.

He previously told The Daily Beast he regretted posting the conspiracies, saying they originated from others.

“I don’t believe anything that these cranks have said, and my life’s work has proven that. As a Congressman, I’ve written a Congressional Resolution condemning a dangerous conspiracy theory, I’ve stood up to MAGA extremists, and I’ve called out the endless bulls–t of the far-right,” his statement to the Daily Beast said.

“I regret posting anything about any of these people. Anyone who looks at my work today knows where I stand.”

But Feal didn’t accept nor believe the apology.

“Bowman’s not sorry. He’s sorry he got caught,” he said.

Feal also brought up Bowman’s fire alarm debacle.

“I question this man’s integrity. We can’t allow people like Santos and Bowman into office,” he said.

Bowman won office in 2020 after toppling veteran ex-Rep. Eliot Engel in the Democratic primary, and he was re-elected in 2022.

But now he faces a serious Democratic primary challenge from Westchester County Executive George Latimer, 70, in the 16th Congressional District that covers southern Westchester and parts of The Bronx.
