During a fundraiser held for Illinois Senator Martin A. Sandoval on Saturday, attendees pretended to assassinate President Trump.

WCIA3 news anchor Mark Maxwell posted photos on Twitter from the event that took place in Winfield. Maxwell tweeted, “A political fundraiser for @SenatorSandoval simulates an assassination attempt against a mock @realDonaldTrump decked out in Mexican garb. Looks like a man pointed a fake assault weapon at the fake President to pose for a picture.”

It is unclear whether Senator Sandoval was aware that the incident happened, but he did respond to CBS News after people on social media began tagging the Secret Service.

“The incident that took place is unacceptable. I don’t condone violence toward the President or anyone else. I apologize that something like this happened at my event,” said Sandoval.
