Acting US Attorney General Matthew Whitaker botched an address to the FBI-NYPD Joint Terrorism Task Force in Manhattan Wednesday by wrongly claiming Chelsea bomber Ahmad Rahimi had two co-conspirators — including one in custody — when he actually acted alone.

“The defendant had two alleged co-conspirators overseas,” Whitaker told dozens of law enforcement officials at the task force’s headquarters.

“One of them attempted to buy a plane ticket to come to America to aid in the attacks. Now he’s getting a plane ride to America — because he’s being extradited.”

After receiving media inquiries, the Justice Department clarified that Whitaker’s prepared remarks originally included references to a defendant other than the Chelsea bomber, but those statements were removed from the speech after a sentencing was postponed.

The department did not identify the other case but said a reference to it “was inadvertently” left in the speech.

Rahimi, the Islamic terrorist and Afghan immigrant, was sentenced to multiple life terms behind bars in February for setting off a bomb that injured 31 people in Chelsea as part of a planned wave of attacks across New York and New Jersey.

Whitaker’s speech came during a two-day visit to New York.

He also visited the National 9/11 Memorial and Museum at the World Trade Center Wednesday morning and met with U.S. attorneys for the region Tuesday evening.
