Maryland's new state prosecutor Emmet C. Davitt declined to comment on the raid, the Associated Press reported.
The state attorney general filed a complaint in court last month alleging that the phone calls telling voters to "relax" violated federal law. His investigation revealed that the phone calls began two hours before polls closed and went out to more than 100,000 Maryland residents. The owner of the company that placed the calls told TPM in November that he was cooperating with the investigation.
The phone calls were intended to suppress turnout for voters supporting Maryland Gov. Martin O'Malley (D), who won reelection.
