YUMA, Ariz. -- The Yuma district office of Rep. Raúl M. Grijalva has been closed for the day after staff members found a shattered window and a bullet Thursday morning.
According to a news release, police are investigating the vandalism and have not released details about a potential motive.
There is no suspect information at this time.
Grijalva intends to open the office again as soon as possible.
Grijalva had to close his Tucson office earlier this year after a Phoenix man threatened to go down and "blow the brains out" of Grijalva and his staff members.
The suspect, Justin M. Haynes, 31, reportedly claimed he was angry over Grijalva's position on immigration issues.
In April, the congressman had called for a boycott of Arizona, but after a judge blocked the implementation of parts of the new immigration law Wednesday, he said national groups should resume holding conventions and conferences in the state.
