MADISON, Wis. (AP) -

A process server says a legislative aide pushed him down when he tried to serve a Republican state senator with a lawsuit.

The Wisconsin State Journal reports the Center for Media and Democracy filed a lawsuit against Sen. Leah Vukmir in June seeking American Legislative Exchange Council records.

According to court documents, Bruce Lowery tried to serve Vukmir on Sept. 3 in her Capitol office. Lowery said Vukmir aide Jason Rostan chased him, pushed him down and called him vulgar names.

Lowery's wife tried to serve Rostan the next day. Rostan held his hands behind his back and refused to accept the papers. She finally touched them to his hands and left them on a desk.

Rostan told the State Journal he followed Lowery but Lowery tripped.
