The group of senators seeking Murphy’s impeachment argue that the Oct. 10 speaking engagement for Trump Jr. and Guilfoyle, his girlfriend, was funded with mandatory student fees in violation of rules banning the use of public students funds to support or oppose a “political party at any level.” In the eyes of critics, Murphy’s correspondence with the Trump fundraising consultant ahead of the event bolsters their case that Trump Jr. and Guilfoyle’s appearance was a campaign event.

“By using student fees to advance his own expressed political beliefs at the expense of the … Student Government writ large, Mr. Murphy not only endangered students marginalized by the speakers’ white nationalist supporters, but also abused his power to advance a particular political party at the expense of the students he should represent,” the impeachment resolution states.

Murphy could not be reached for comment late Tuesday, but he has previously maintained in comments to the student newspaper, the Independent Florida Alligator, that the couple’s speech was not a campaign event and therefore didn’t violate any rules.
