BALTIMORE (WJZ) — The FBI quietly raided a Republican consulting and fundraising firm that works with Republican candidates in Annapolis Thursday.

It’s still unclear why FBI agents spent hours inside gathering evidence.

The FBI says this is part of a Washington D.C. field office investigation.

Agents turned off elevator access to the third floor of 191 Main Street, where Strategic Campaign Group is housed, and used trash bags to cover the office windows while they gather evidence.

They came prepared with a warrant to search the office and take files.

The firm has a good reputation among Maryland Republicans, but a raid from the FBI was enough for some to start pulling away.

Republican Delegate Nic Kipke says he was shocked. He went on to say until the investigation is concluded and they’re cleared, he won’t be using their services.

WJZ spoke with a client who said the company’s CEO told him the raid stemmed from a 2013 campaign for a politician in Virginia, Ken Cuccinelli, who ran for governor but lost.

The company’s work led to a lawsuit after Cuccinelli lost to Terry McAuliffe.

The president of the firm also told the Baltimore Sun that the federal investigation ties back to the 2013 Virginia gubernatorial campaign.

Chairman of the State GOP party, Dirk Haire, says “we don’t believe anyone currently has an engagement with that firm, so we are simply suggesting that no one should engage them for any activities at the present time until the investigation is resolved.”

The Maryland Republican Party also confirms it’s looking into the raid.

All the feds will say is that this is an active and ongoing investigation.
