Last weekend’s shootings in Tucson have prompted a string of resignations from within a local Republican Party in Arizona.

Anthony Miller, who was recently re-elected to a second term as chairman of the Arizona Legislative District 20 Republican Party, stepped down from the post hours after the shooting, citing safety concerns.

“Today my wife of 20 yrs ask [sic] me do I think that my PCs (precinct committee members) will shoot at our home? So with this being said I am stepping down,” Miller wrote in an e-mail to the state Republican Party chairman, according to the Arizona Republic.

Miller said local tea party members had made verbal and online attacks against him after he won the election. Three other members of the local group also reportedly resigned, with at least one saying the “focus on ‘getting’ Anthony” was the reason.

Arizona’s District 20 includes the Phoenix suburbs of Chandler, Tempe, and Ahwatukee Foothills and is more than 100 miles from Democratic Rep. Gabrielle Giffords’ House district where the shootings took place.
