Maryland Gov. Larry Hogan (R) will be called by prosecutors as a witness in the trial of his former chief of staff, who is accused of defrauding a quasi-governmental agency, a new filing in the case suggests. Roy C. McGrath was indicted last year in connection to a nearly quarter-million-dollar severance package he received from the Maryland Environmental Service (MES), where he served as executive director before becoming Hogan’s top aide in 2020. McGrath’s federal trial, which is scheduled to begin on Oct. 24, will center partly on whether Hogan approved or consented to the payment of $233,647.23, which McGrath arranged to receive as he left as director of the Maryland Environmental Service to work for the governor.
