Efforts to sway Federal Bureau of Investigations officials into relocating their new consolidated headquarters to Prince George’s County, Md., reached a pinnacle recently when U.S. Sen. Barbara Mikulski (D-Md.) announced the inclusion of a $390 million set-aside to facilitate its building.

“I’ve fought tooth and nail for the men and women of the FBI, just as they fight each day to keep our communities safe from criminals and terrorists,” Mikulski said in a statement. “This is a headquarters that belongs in Prince George’s County.”

While the federal General Service Administration would cover the majority of the cost of moving, Mikulski’s provision included $180 million for the FBI in new construction funds, $135 million from funds not spent in prior years for land acquisition and other pre-construction work, and $75 million for the GSA for management and oversight.

Though a choice has yet to be made between the three potential sites for the new headquarters – two in Prince George’s County (Greenbelt and Landover) and Springfield, Va., the county sites are believed to have the most potential.

“I was proud to join Sen. Mikulski and Team Maryland to announce this initial, historic, and major down payment of $390 million on a new, fully-consolidated headquarters for the Federal Bureau of Investigation (FBI),” said Congresswoman Donna Edwards (D-Md.) in a statement.  “This funding is a huge step forward to ensure the employees of the FBI receive a fully-consolidated facility that provides the most modern and best environment to achieve their security mission in the 21st Century and makes the smartest use of taxpayer dollars.”

Key members of Team Maryland – a delegation of Maryland leaders, including County Executive Rushern L. Baker III (D) celebrated Mikulski’s efforts.

“From the very beginning, Team Maryland’s been unified at the federal and state level, and through two Governors,” Baker said.  “I am grateful for Sen. Mikulski’s leadership in this effort, and I know all of Team Maryland will continue working together to bring the FBI to where it belongs: my home, our county – Prince George’s County.”
