This is a screenshot of Drexel University professor George Ciccariello-Maher's latest controversial tweet.

Three Republican state senators are calling on Drexel University to fire a professor for a social media post disparaging an airline passenger who gave up his first-class seat for a uniformed soldier.

Professor George Ciccariello-Maher, who came under fire for another controversial tweet in December, posted on March 26 about that passenger's act of giving up his plane seat, "People are thanking him. I'm trying not to vomit or yell Mosul," referring to the Iraqi city where the U.S. military has been accused of killing hundreds of civilians in an airstrike against the Islamic State.

In a letter (see below) to Drexel President John Fry, Senate President Pro Tempore Joe Scarnati, R-Jefferson County, Sens. John Rafferty, R-Montgomery County, and Ryan Aument, R-Lancaster County, said, "Professor Ciccariello-Maher once again used obviously inflammatory comments to promote his own shocking brand to the detriment of the reputation of Drexel," the senators said in their letter.

"We are confident that continuing to employ this hateful and disgusting man will do nothing but tarnish the Drexel name. We encourage you to terminate him as soon as possible."

Aument, who served as an Army Captain in Iraq, found the professor's post to be personally offensive and said it should not be tolerated by the university.

Drexel University spokeswoman Niki Gianakaris said, "Any review of Drexel University Professor George Ciccariello-Maher is a personnel matter and as such will not be discussed publicly."

The professor's latest tweet is drawing national media attention just as another did in December when Ciccariello-Maher posted: "All I want for Christmas is White Genocide," which he said was satire but Drexel called "utterly reprehensible."

On March 31, Drexel issued a statement about the professor's most recent tweet, saying, "The recent social media comments by George Ciccariello-Maher, associate professor of Politics and Global Studies at Drexel, were made outside the classroom, are his own opinion and do not represent the University's views.

"Drexel is committed to and vigorously supports our ROTC students, students on active duty and reserve, and students, faculty, staff and alumni who have served in the military. Our support for military-affiliated members of our community has helped us create an inclusive campus culture that honors service and Drexel's deep connection to American military history."

An attempt to contact Ciccariello-Maher for comment about the senators' call for his firing was unsuccessful on Thursday.
