PHOENIX (AP) -- Arizona Sen. Don Shooter says he should have been more patient and waited to meet with school officials instead of barging into his grandson's classroom and verbally threatening his teacher.
Shooter said in a statement Friday that the teacher had created a hostile environment after she refused to let his grandson go to the bathroom when he was sick and called him "retarded."
Yuma police say Shooter went to the school on March 22 and is being investigated on potential charges of assault, trespassing and disrupting a school.
Students, teachers and administrators were alarmed when a visibly agitated Shooter slipped past a receptionist who had told him he couldn't enter the school.
Shooter is a tea party leader who chairs the Senate Appropriations Committee. He took office in 2010.
