One more Republican investigated

This time, it's Duke Cunningham's successor. They're falling like pins in a bowling alley:

NORTH COUNTY [Carlsbad, CA]----- A neighbor of Republican 50th District Rep. Brian Bilbray said Thursday that he was subpoenaed to testify before a San Diego County grand jury in August and spent about an hour and a half answering questions about whether Bilbray lived in his Carlsbad neighborhood.

…Speculation has swirled around the Bilbray's residence issue for days, with Democrats and Busby's campaign claiming they had received calls from several of Bilbray's Carlsbad neighbors, saying they had been called to testify before a grand jury investigating the congressman's residence.
