GOP presidential front-runner Donald Trump said Monday that he wants apologies from those who doubt his recollection of the 9/11 terrorist attacks.

“I want an apology,” he tweeted. “Many people have tweeted that I am right.”

{mosads}Trump provoked outrage by repeatedly claiming that he saws thousands of people in parts of New Jersey with heavy Arab populations cheering the fall of the World Trade Center on Sept. 11, 2001. 

Trump on Monday tweeted a Sept. 18, 2001, article from The Washington Post titled, “Northern New Jersey Draws Probers’ Eyes.” 

“In Jersey City, within hours of two jetliners’ plowing into the World Trade Center, law enforcement authorities detained and questioned a number of people who were allegedly seen celebrating the attacks and holding tailgate-style parties on rooftops while they watched the devastation on the other side of the river,” the article reads.

Trump first said Muslims cheered on 9/11 during comments at a rally on Saturday in Birmingham, Ala.

“[The twin towers] came tumbling down,” he said. “And I watched in Jersey City, New Jersey, where thousands of people were cheering as the building was coming down.”

The outspoken billionaire then defended his memory during an interview with ABC News host George Stephanopoulos early Sunday.

“George, it did happen,” Trump said on ABC News’s “This Week.” “I know it might not be politically correct for you to talk about it, but there were people cheering … as those buildings came down.

“And that tells you something,” he added. “Not good.”

New Jersey Gov. Chris Christie, another Republican White House hopeful, said later Sunday that he has no recollection of the events Trump describes.

“I think if it happened, I would remember that, but, you know, there could be things I forget, too,” he said. “But I don’t remember that, no.”

The Anti-Defamation League, meanwhile, criticized Trump’s account as “factually challenged.”
