ANCHORAGE, Alaska (AP) — A painting on display at the University of Alaska Anchorage depicting a naked actor holding President Donald Trump's head has sparked discussion.

University officials are defending the painting titled "Everything," by Thomas Chung, KTVA-TV reported (http://bit.ly/2pW2GQy) Wednesday.

"The art installation at UAA that has sparked recent concern and debate has people asking whether a public university should be home to controversial, or even offensive, ideas," University of Alaska President Jim Johnson wrote in an email. "A vital and vibrant university, regardless of the campus, must be a place of ideas, opinion, and debate."

The painting shows Chris Evans, who plays Captain America, naked and holding Trump's head in his left hand and a sign in his right. Former Secretary of State Hillary Clinton is shown wrapped around Evans' leg.

University Chancellor Tom Case said the painting has "sparked spirited discussions," but that freedom of expression is fundamental to the university's mission.

"We understand that some may not support this exhibit, but universities — including UAA — are a place for free exchange of ideas, diversity of thoughts and of opinions, and ideally, a place for conversation to occur around our differences and similarities," Case said in a written statement.
