State and Federal Authorities Are Said to Be Probing Hogan’s Ex-Chief of Staff

​State prosecutors and federal authorities are investigating Roy McGrath, Gov. Lawrence J. Hogan Jr.’s former chief of staff, Maryland Matters has learned.

McGrath stepped down as Hogan’s top aide in August, following media reports that he pressed his prior employer, the Maryland Environmental Service, into awarding him a year’s severance when he left the quasi-governmental agency to join the governor’s team.

McGrath spent three years as CEO of the public works and environmental services agency before being tapped to serve as Hogan’s chief of staff.

The severance payout of $234,000 — along with more than $50,000 in travel, training and other expenses he was reimbursed for upon his departure — quickly became a source of controversy, and McGrath abruptly stepped down as chief of staff after just 11 weeks on the job.
