Some 200 students at the conservative Brigham Young University peacefully protested Wednesday against a planned appearance by U.S. Vice President Dick Cheney.
Cheney is scheduled to be the main speaker at the Utah university's graduation ceremony April 26.
The protesters at the largely Mormon university complained about Cheney's ties to the war in Iraq, among other issues.
Meanwhile, supporters of Cheney's visit staged a counter-protest and circulated a petition thanking the vice president for his upcoming visit.
Tuesday night, just over a dozen students at American University in Washington, D.C. protested an appearance by presidential aide Karl Rove. Officials said the students threw objects at Rove and tried to lie down in front of his car. He was emerging from an invitation-only speaking engagement for the school's College Republicans.
