Kenneth Glover, the president and chief administrative officer of Dimensions Healthcare System, who has been a major focus of an internal investigation by the hospital system, has resigned, according to officials.

Glover, who served in his position for 18 months, submitted his resignation on Monday.

Dimensions Healthcare System hired a former Maryland attorney general and federal prosector in December to examine allegations that at least one top company executive traded promises of lucrative contracts with former Prince George’s County Executive Jack B. Johnson in exchange for his job at the hospital.

Johnson was sentenced to seven years in federal prison in a widespread bribery scheme that involved pocketing hundreds of thousands of dollars from developers and business owners in exchange for favors. During wiretapped conversations, Johnson bragged about the number of jobs he’d arranged and the money he planned to make after he left office.

Nichols said the board will meet soon to find a replacement for Glover.
