Andrew Hitt, chairman of the Wisconsin Republican Party, has called for a federal investigation into an African American who was shot dead in broad daylight near his “Vote Trump” banners on Thursday, July 24.

“It is tragic to learn of the senseless murder of Bernell Trammell, and I offer my sincere condolences to his family and friends,” Hitt wrote. “Because of Trammell’s well known political activism and the possibility that his murder could be politically motivated, I respectfully request that United States Attorney Matthew Krueger open an investigation into this heinous crime.”

“No American should fear for their personal safety because of where they live or their political affiliation,” he added.

Tremmell, 60, was well-known in his Milwaukee community for his support for President Donald Trump. He was often seen in public holding homemade signs urging people to re-elect the president in November. Tremmell was fatally shot Thursday afternoon outside his small business in Milwaukee’s Riverwest neighborhood.

“I had an interaction with him last Saturday across the street from Walmart on Capitol Drive,” one woman who did not wish to be identified said. “It was the second time I had seen him with his Trump sign and I pulled my car over to chat with him. What a nice, friendly man! We chatted for several minutes, and I told him I was proud of him and he’s very brave to put himself out there so visibly as a Trump supporter!”

According to the Milwaukee Journal Sentinel, police do not yet know the motive for the murder since they have not yet made any arrests.

Adebisi Agoro, a local blogger, who spoke with Trammell just hours before the shooting, told the journal that Trammell was a “positive guy” and “Milwaukee character.” He said Trammell had many signs in his shop, most of which appear religious or political in nature , including a “Black Lives Matter,” “Thumbs Up Before Guns Up,” and “Repent” sign.

“He’s just a community figure,” Agoro told Fox 6. “I respected him just because he had a position. … He’s got his opinion on why he feels that way; and I’m not going to knock him.”

In a video that Agoro documented of the encounter the morning Trammell died, Trammell told him why he supported the president.

“I believe that Trump is the sign of the times,” Trammell said.
