PHOENIX (AP) - A Democratic member of the Arizona House has apologized to his colleagues for a Facebook post where he said he wanted to punch the Republican sponsor of a school voucher bill in the throat.

Rep. Jesus Rubalcava told his colleagues Thursday that his post was "definitely unprofessional and unacceptable and I want this body to know that I have apologized to Sen. Debbie Lesko for my comment and I sincerely apologize."

The freshman lawmaker from Gila Bend posted the comment after Lesko's bill vastly expanding the state's private school voucher program passed last week. Gov. Doug Ducey quickly signed the measure.

Lesko said she appreciated the apology. But she called the comment itself "very disturbing and totally inappropriate."

The comment was first reported by the Arizona Capitol Times.
