Prince George’s County Executive Rushern L. Baker III has tapped a former D.C. government official to become his new top aide, replacing Brad Seamon who is resigning to return to the private sector.

Nicholas A. Majett, former director of the Department of Consumer and Regulatory Affairs for the District, will begin leading the county executive’s team starting May 5, officials said.

As acting Prince George’s chief administrative officer, Majett will manage the daily operations of government agencies and continue to push Baker’s signature programs initiated during Seamon’s tenure.

“We have made incredible progress and improvements throughout county government and in our communities and I am confident that Nick Majett is the type of leader we need to help us continue to move this county forward,” Baker said in a statement.

Majett has held several positions in D.C. government including as an assistant attorney general prosecuting tax and government fraud cases. The Howard University alum will be permanently appointed at a later date, the administration said.

Earlier this month, Seamon announced he would be leaving Baker’s administration after working closely with his friend, Baker, to implement the executive’s initiatives.

He engineered Baker’s Transforming Neighborhoods Initiative using data to target communities in Prince George’s with the lowest quality of life measures, such as high crime rates.

Seamon was also instrumental is pushing forward a deal to build a new regional medical center in Largo that is expected to open in 2017. The 52-year-old will return to running Seamon Corp., a federal contracting business he founded with his wife.
