Duquesne University has forbidden TV personality Geraldo Rivera from moderating an upcoming panel following a half-naked selfie he posted on Twitter this summer.

The university officials allege that the picture, taken from a cell phone and posted in July on the social media website, was declared inappropriate according to the values of the Catholic university.

"We warn our students not to put anything inappropriate on social media because of potential consequences - you could consider this teaching by example," Spokesperson Bridget Fare said.

The picture in question was immediately removed from Twitter. The picture, taken in a bathroom mirror, reveals a 'loose-fitting, low-hanging white towel over his most private parts.'

"70 is the new 50," he tweeted in July, showing off his abs.

Later, Rivera admitted that he took the picture after a few shots of Tequila.

"This weekend, it was tequila. I never do tequila when I'm alone, but I had this new bottle that someone had given me for my birthday," Rivera said. "By the second one, my fate was sealed."

The 70-year-old moustachioed reporter was reportedly invited to moderate a panel to commemorate the 50th anniversary of President John F. Kennedy's assassination.

Responding to the cancellation by the academic institute based in Pennsylvania, Rivera posted a series of tweets by saying:

"Just heard Duquesne Univ cancelled my appearance at JFK assassination panel because of 'selfie'. Fact I first aired Zapruder film less impt."

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

Rivera feels that the cancellation was 'incredibly rude.'

"Are all prospective speakers similarly scrutinized, or is my sin receiving special attention?" Rivera said. "Does the 'selfie' over-weigh my Peabody, Emmys, RFK's and other professional achievements on Duquesne's scale of morality? Are the students of Duquesne so sensitive and protected that they will be unable to concentrate on the topic being discussed because they cannot unsee the image?"

Despite Rivera's half-naked self-portrait, he garnered much support from the Twitterati, including Columbia University prof, Marc Lamont Hill.

"they did the same to me last year."
