Associated Press: The mayor of an eastern Idaho town where second- and third-grade students on a school bus chanted "assassinate Obama!" after the Nov. 4 election has publicly apologized, saying there's no excuse for such behavior.

Rexburg Mayor Shawn Larsen wrote in a guest editorial sent Tuesday to local newspapers that he was saddened by the notoriety his community had received over the incident, both across the United States and abroad.

Larsen told The Associated Press that a formal response to the incident in his city was sorely needed.

"When people don't stand up and say, 'That's not appropriate, that's wrong, and those are hateful remarks,' it's almost like they are saying that it's an OK thing to do. And it's not," he said. "The mayor doesn't have any authority over the school system, but I do think it reflects upon the community."

In his editorial, Larsen recounted seeing Barack Obama speak in Washington, D.C., in early 2006 about his faith and how his upbringing had influenced his policies and his priorities. Larsen said he left the event inspired.

Idaho voters overwhelmingly favored Republican John McCain in the presidential election. In Madison County, where Rexburg is located, 85 percent of voters chose McCain over the Democratic candidate, and some claim it's the "reddest county" in America.
