CHEYENNE, Wyo. (AP) — Rapper and music producer Kanye West’s campaign ran into trouble with the law Tuesday on his first day of trying to get on the presidential ballot in his home state of Wyoming.

People gathering signatures on behalf of West and another presidential candidate got too close to polling locations during the state’s primary, election officials said.

The signature-gatherers for West and candidate Brock Pierce refused to keep at least 100 yards (91 meters) away, prompting election workers to call police and sheriff’s deputies at five of the seven polling locations in and around Cheyenne, Laramie County Clerk Debra Lee said.

“Some of them became quite aggressive and refused to leave,” said Lee.

Election officials at Laramie County Community College confiscated a sign that read “registered voters sign here” on one side and “Kanye West” on the other, potentially causing people to falsely believe they needed to sign West’s petition in order to vote, Lee said.

Social media messages seeking comment from West agent Trevian Kutti and Pierce weren’t immediately returned Tuesday. Election officials in Casper, where a state elections official said similar violations occurred, didn’t immediately return a phone message seeking comment.

Such incidents don’t affect whether the signatures count as valid or not, said the secretary of state’s office spokesman Will Dinneen.
