Donald Trump is blaming television for its role in a controversy that has been brewing for the past week over the GOP presidential candidate’s claim that he saw video of thousands of Muslims in New Jersey celebrating after the World Trade Center fell in the 9/11 terrorist attack.

Deadline.com reports that Trump pointed the finger at TV during an appearance today on MSNBC’s “Morning Joe,” blaming the medium for failing to produce proof of his claim.

Asked by host Joe Scarborough whether Trump was standing by the claim, Trump offered an explanation for the lack of video proof, saying: “Don’t forget … 15 years ago, it wasn’t like it is today, where you press a button and you play a video. Fourteen, 15 years ago, they don’t even put it in files, they destroy half of the stuff.”

Trump added: “They’ll find something. They’re going to find something.”

Trump also addressed the issue Sunday on NBC’s “Meet the Press,” insisting that he knows people witnessed the incident in person. “I’ve had hundreds of phone calls to the Trump Organization saying, ‘We saw it. There was dancing in the streets,’” Trump said on the show.

Deadline notes that “Meet the Press” host Chuck Todd interjected: “They want to agree with you — that doesn’t make it true.”

Trump was steadfast, telling the host: “Chuck. I’ll tell you, I have a very good memory. I saw it somewhere on television many years ago, and I never forgot it — and it was on television, too.”
