U.S. Senate candidate Graham Platner’s national finance director said Friday he is resigning from the campaign, citing differences in “professional standards.”
The announcement from Ronald Holmes represents the latest shake-up for Platner’s campaign following a string of controversies. Platner’s political director also resigned earlier this month, and his campaign manager announced earlier this week he would be leaving.
“I joined this campaign because I believed in building something different — a campaign of fresh energy, integrity, and reform-minded thinking in a political system that often resists exactly those things,” Holmes said in a post on LinkedIn. “Somewhere along the way, I began to feel that my professional standards as a campaign professional no longer fully aligned with those of the campaign.”
Platner, a 41-year-old military veteran and oyster farmer, is seeking to challenge Republican Sen. Susan Collins for her seat in 2026, though he’ll have to make it through the Democratic primary featuring Gov. Janet Mills and others first.
In recent weeks, Platner’s campaign has been 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.
Earlier this week, Platner’s campaign manager, Kevin Brown, stepped away after less than a week on the job, saying it was because he found out his wife was going to be having a baby.
Platner’s campaign did not immediately respond to a request for comment Friday.
