Thomas McGonigle, who serves as chief of staff to Delaware Governor Jack Markell, will step down from the position next month to manage the Wilmington, Del., office of Drinker Biddle & Reath. Mike Barlow, who is now chief legal counsel to the governor, will take over as chief of staff, the administration announced earlier this month. Barlow and McGonigle said Markell will now seek to fill Barlow’s present position.

McGonigle will resign from his current position later this month and will join Drinker Biddle on December 10. He will serve as outside general counsel for the firm and run its 10-attorney Delaware office.
