Congressional candidate Doug Slocum of Macomb County boasted in a Facebook post that he had attended a pro-President Trump gathering along with members of the far-right political group known as The Proud Boys.

Slocum, the former commander of the Selfridge Air National Guard Base in Harrison Township, wrote on Facebook about his attendance at the local “Trump Unity” event on Dec. 20: “Had a wonderful evening fundraising for the Trump Unity Bridge with Rob Cortis, The Proud Boys, Brian Pannebecker, Auto Workers for Trump, Casey Armitage, Adam Armitage, Marty Prehn, Bob Little, Don Brown, Lisa Damon and other great Trump Republican friends.”

The Proud Boys are a high-profile neo-fascist group that glorifies violence against left-wingers and has some ties to white nationalist groups. They have been associated with racism, Islamophobia, anti-Semitism and misogyny. The group, known for its hazing rituals, only allows men as members.

Slocum, a retired Air Force Brigadier General, is running in the territory where GOP Rep. Paul Mitchell is vacating his seat, in the same district that was represented by Candice Miller for 14 years. The 10th Congressional District extends from northern Macomb County to the tip of the Thumb Area.

Among the others mentioned in Slocum’s online message are two controversial characters from the Macomb GOP.

Pennebecker is an anti-union activist who has repeatedly referred to Democrats as communists and has advocated carrying guns in churches to protect against Muslims who want to massacre “infidels.”

Prehn (pictured above, right, with Slocum) has been a provocative figure for many years in Macomb County, dubiously portraying himself as an expert on elder abuse, a criminal investigator and a champion for families facing Probate Court fights over guardianship.
