Davis, who is serving his seventh term in the House of Representatives, told WBBM-TV in Chicago he was driving three friends home early Monday morning when two white police officers pulled him over and told him he had crossed the center line.
Davis said he was given a $75 ticket, but he insists he did nothing wrong.
"I hope that this was some kind of isolated instance, but I know in my heart of hearts, I know that it's not," he told CBS 2. "There was just no reason I could conjure up other than the fact that there were four black people in a car."
Chicago police confirmed a ticket was issued but did not respond to Davis' claim that he was pulled over for what is often called "driving while black."
Davis said he intends to fight the ticket, and he said racial profiling should be stopped.
