Former Prince George’s County State’s Attorney Glenn F. Ivey is planning a run for Congress.

Ivey, (D) of Cheverly, who served as the county’s top prosecutor from 2003 to 2011, will file paperwork within the next few days to challenge incumbent Rep. Donna Edwards (D-Dist. 4) of Fort Washington in the 2012 election, according to Ramon Korionoff, who was Ivey’s spokesman when he was state’s attorney and is now working as a media consultant for him.

“Mr. Ivey is laying the groundwork for a congressional run,” Korionoff said. “Public service runs in his blood.”

Both Ivey, 50, and Edwards, 53, who has been in office since 2008, declined to comment.

Ivey is now a partner at the Washington, D.C., branch of the Venable law firm, where he specializes in white-collar criminal defense and general civil litigation.

In 2009, Ivey announced he was creating an exploratory committee for a possible run at the District 4 seat, but he decided not to run for the office, citing a desire to complete his state’s attorney term and spend time with his family.

Until this month’s special session of the Maryland General Assembly, District 4 included portions of Prince George’s County and Montgomery County. But the new district map, signed into law last week by Gov. Martin O’Malley (D), replaces the Montgomery portion with a section of Anne Arundel County.

Edwards has criticized the revised district map, which she said reduces minority representation in Montgomery County.

Edwards may also face a challenge from Anne Arundel County Councilman Jamie Benoit (D-Dist.4) of Crownsville, who announced Tuesday he was forming an exploratory committee.

Benoit, 40, said in a statement that Edwards is “posturing for the general public instead of focusing on what matters: putting Americans back to work.”
