Federal prosecutors have charged a Lake Forest man in connection with the deadly January 6 insurrection at the U.S. Capitol Building in Washington D.C.

Mark Kulas, Jr., 27, of Lake Forest, was charged in U.S. District Court for the District of Columbia with one count of violent entry and disorderly conduct on Capitol grounds, a misdemeanor.

Kulas was charged by criminal information on Friday and court records were unsealed publicly on Monday.

Prosecutors allege Kulas willfully and knowingly paraded, demonstrated and picketed in the U.S. Capitol Building, according to court documents.

Mark Kulas’s brother, Christian Kulas, of Kenilworth, was charged five months ago in early June for also participating in the riot.

Several people sent tips to the FBI days after the January 6 riot about a video Christian Kulas had posted on Instagram that appeared to show himself participating.

A man, who multiple people identified as Christian Kulas, was seen in the video wearing a Burberry jacket along with a baseball cap that said “Keep America Great” on the front of it, according to an affidavit from the FBI.

He could be heard in the video laughing and saying “storming the Capitol,” the affidavit said.

Kulas’ mother confirmed in a direct message on social media that her son Christian was the one in the video, the affidavit said.

The Kulas brothers are graduates of Lake Forest High School and are the sons of the owners of Kulas Maids, which is a Northbrook-based company.

The Kulas brothers are both scheduled to appear in court on December 6 in front of U.S. District Court Judge Thomas Hogan for plea agreement hearings.

In the ten months since January 6, prosecutors said that more than 675 individuals have been arrested in nearly all 50 states for crimes related to the breach of the U.S. Capitol, including over 210 individuals charged with assaulting or impeding law enforcement.
