Geraldo Rivera may have a sense of humor about the stripped-down "selfie" he tweeted and then deleted in July, but the news personality is still feeling the repercussions from the nearly nude photo.

Rivera was slated to join a panel at Duquesne University, in Pittsburgh, next month to discuss the assassination of President John F. Kennedy; however, the newsman tweeted he had been dis-invited because of his "selfie" - and he isn't happy about it.

"Duquesne's cancellation of my JFK panel appearance is pretentious censorship. Do students agree with administration? Am I banned for life?" Rivera tweeted on Monday.

The JFK panel is scheduled to take place from Oct. 17-19 and marks the 50th anniversary of the president's assassination.

In 1975, Rivera was the first person to air Abraham Zapruder's home video on a national network, which captured the president's assassination on tape.

A representative from Duquesne did not immediately respond to a request for comment. But a spokeswoman told the Pittsburgh Post-Gazette that Rivera's "selfie" was "inappropriate and inconsistent with who we are as a Catholic university."

Rivera's photo showed the shredded 70-year-old newsman wearing rose-colored glasses, shirtless and with a towel draped around his hips. He captioned it "70 is the new 50."

The photo spawned countless jokes on Twitter, prompting Rivera to make light of the situation after he deleted the "selfie."

"Note to self," he wrote, "no tweeting after 1am."
