Roy McGrath was Hogan's chief of staff for two months in 2020, until The Baltimore Sun broke news of a $233,647 severance he received in 2020 upon leaving the Maryland Environmental Service to take the chief of staff position. Hogan denied knowing of the severance payment, and ordered an audit of the Maryland Environmental Service following his resignation. McGrath was facing wire fraud and embezzlement charges and became a fugitive when he failed to show up to federal court in Baltimore in a trial wherein Hogan was to be called as a witness. McGrath died on April 3, 2023, after receiving a gunshot wound in a confrontation with FBI agents in Knoxville, Tennessee, that day.
