ANN ARBOR, MI - A man charged for having a gun in connection with a March incident involving supporters and opponents of white nationalist Richard Spencer has pleaded guilty.

Jonathan Kolanowski pleaded guilty, Aug. 30, to one felony count of carrying a concealed weapon, court records show.

The charge stems from a road rage incident that occurred March 4 in Pittsfield Township while Kolanowski was driving people to the Spencer event at Michigan State University, which was to take place the next morning.

Kolanowski called police that day to report a vehicle was chasing him from Livingston County to Washtenaw County's Pittsfield Township.

A representative from Great Lakes Antifa, an anti-fascist activist organization, told The Ann Arbor News previously that members of their group ran into Kolanowski with a group of friends at a Staples store at 2601 Jackson Ave. in Ann Arbor earlier in the evening March 4.

They claim Kolanowski drove his SUV at one of the activist's vehicles and they began chasing him.

When officers arrived on the scene on Washtenaw Avenue, they found two vehicles pulled over. People in the second car told police Kolanowski had pulled out a pistol and waved it at them to scare them off, police said previously.

Police searched his vehicle and found a handgun registered to him.

Kolanowski had a concealed pistol license, but it was suspended in December 2017 due to a pending domestic violence case in Macomb County, records show.

He told police he did not know his concealed pistol license was suspended when he was arrested.

During his preliminary examination, it was shown the notice was delivered to his previous home around the time he moved from that address.

The court did not believe Kolanowski's claim that he did not receive the notice, arguing that forwarding mail from an old address to a new one is part of the moving process, records show.

Kolanowski is scheduled for sentencing Oct. 4 before Washtenaw County Trial Judge Darlene O'Brien. He is currently free on $2,000 bond.

Spencer's appearance at Michigan State University, March 5, resulted in 25 people being arrested, according to MSU police. Thirteen of the arrests were for felony charges, including resisting and obstructing police officers and carrying a concealed weapon.
