Professors resign after University of Virginia hires former Trump official Two professors resigned Monday after UVA hired a Trump official.

In the latest backlash against current and former Trump administration officials, two history professors announced their resignations Monday from a public policy center after the University of Virginia hired President Donald Trump’s former legislative affairs director Marc Short.

“The appointment of Mr. Short [as a paid senior fellow] runs counter to the [Miller] Center’s fundamental values of nonpartisanship, transparency, openness, a passion for truth and objectivity, and civility,” professors Melvyn Leffler and William Hitchcock wrote in a July 30 letter to William Antholis, the UVA-affiliated center's director.

Their resignations come amid calls from several progressives to confront Trump officials, including from Rep. Maxine Waters, D-Calif., who called on supporters last month to tell Trump Cabinet members “they’re not welcome anymore, anywhere.”

Leffler and Hitchcock cited Short’s “ongoing attacks on a free media” and association with “rhetoric and policies that have empowered and emboldened white supremacists” as reasons for their resignation.

Antholis defended Short’s appointment in a statement, noting he “brings a missing critical voice—one that represents members of Congress and the Republican Party who continue to support the president in large numbers" and furthers the Miller Center's mission to study the American presidency.

Short has not immediately responded to an ABC News request for comment but earlier expressed disappointment at faculty members' opposition to his hiring.

“There is an irony at Thomas Jefferson’s university that professors are seeking to silence debate instead of fostering civil conversation,” he told The Washington Post in a statement last week.

The professors also pointed to a lack of “adequate discussion, deliberation, and a vote” among faculty members prior to Short’s appointment.

But Antholis told ABC News “it’s not typical” to consult with faculty for fellowship appointments.

“This is not a faculty appointment, so it’s entirely at the discretion of the director,” he said, adding that for this specific appointment, “there was much deeper and wider discussion than usual” with Miller Center governing council members, including L.F. Payne, a former Democratic congressman who used to work with Short at a consulting firm.

"I'm very sad about the resignations, but we have to commit to understanding all the presidencies -- the ones we like and the ones we don't. Marc is someone who's always supported and worked with his colleagues, and is a man of personal integrity," Payne told ABC News.

Antholis likened Short’s appointment to adjunct or visiting faculty appointments, which he said come at the discretion of department chairs without a need for faculty consultation.

“The loss of any Miller Center faculty or staff member saddens me. As much as I respect the depth of feelings on this issue, the Miller Center’s core focus on the presidency, our commitment to nonpartisanship, and our demonstrated ability to promote civil discourse must remain our principal responsibility, especially in trying times,” he said in a statement.

Antholis believes his decision to appoint Short to a one-year, paid senior fellowship beginning August 1 will help the university better understand the Trump presidency, which he acknowledged is “disruptive and dangerous.”

In their resignation letter, Leffler and Hitchcock said Short’s appointment is “especially egregious” given that it comes close to the one-year anniversary of the Charlottesville white nationalist protest, which occurred last August on UVA’s campus.

“Until his appointment to a fellowship at UVA, Mr. Short did not distance himself from President Trump’s remarks about [Charlottesville]...by not emphasizing the threats to human decency posed by the public display of Nazi symbols and racist diatribes in our own neighborhood, Mr. Short was complicit in the erosion of our civic discourse and showed an appalling indifference to the civility of our own city and university,” Leffler and Hitchcock wrote.

Antholis told ABC News he “understands the frustrations people feel” about the Trump administration, but hopes to give Short the “opportunity to help us understand the presidency better.”

“I made a judgment on [Short]. His beliefs fall within the legitimate bounds of political discourse. I would hate to judge someone based on prior service in a presidential administration,” he said, noting that he himself previously served in the Clinton administration and would “hate to be judged for it.”
