Graham Platner’s campaign manager is stepping down after less than a week on the job because he and his wife are having a baby.

Kevin Brown, who served as the senior adviser to Sen. Elizabeth Warren’s presidential campaign, was on the job for less than a week. His departure appears to be unrelated to a string of controversies surrounding Platner, a first-time candidate seeking the Democratic nomination for U.S. Senate.

“Graham is a dear friend,” Brown said in a written statement Monday. “I started this campaign Tuesday but found out Friday we have a baby on the way. Graham deserves someone who is 100% in on his race and we want to lean into this new experience as a family so it was best we step back sooner than later so Graham can get the Manager he deserves.”

Platner’s campaign did not respond to questions about whether an interim or permanent manager has been named.

The departure is the latest shake-up for Platner’s campaign, which has been embroiled in controversies for nearly two weeks.

Platner, a 41-year-old military veteran and oyster farmer, has seen his campaign hampered by a series of old social media comments on Reddit that have made national headlines and prompted his Maine political director, Genevieve McDonald, a former state lawmaker, to resign.

Platner’s past comments include posts calling all cops “bastards,” rural white Americans racists and stupid, and saying that violence may be necessary to combat fascism. He also asked why black people don’t tip, used anti-gay slurs and made dismissive comments about sexual assault in the military.

Platner has apologized for the comments, which he said he made while suffering from untreated PTSD and depression, after four deployments to war zones in Iraq and Afghanistan.

Last week, his campaign disclosed his skull-and-crossbones tattoo that resembled a Nazi symbol, which he said he got as a Marine while drunk on shore leave nearly 20 years ago. He said he only recently learned of its connection to Hitler’s SS and had it covered last week.

Other candidates running in the Democratic primary include two-term Gov. Janet Mills, former Capitol Hill staffer Jordan Wood and David Costello, of Brunswick.
