The manager of Graham Platner’s campaign for U.S. Senate in Maine is stepping down for family-related reasons.

Kevin Brown, who was also an adviser on Sen. Elizabeth Warren’s presidential campaign, says he found out on Friday that he and his wife are having a baby.

Brown was on the job for less than a week.

The departure comes as the campaign weathers a string of controversies, including online comments made by Platner years ago that recently resurfaced and a tattoo of a symbol associated with Nazis he recently had covered up.
