The Chicago nightclub that would not admit six black students from Washington University has agreed to issue an apology and to participate in a demonstration in Chicago next month about racial discrimination, the students said.

In addition, the management company that runs The Original Mothers nightclub will mandate that the managers at all its clubs undergo diversity training. And the club has agreed to host three fundraisers in coming months — the proceeds of which will go to yet-to-be determined community groups. A fourth event will be held in St. Louis.

The six Washington U. seniors and the class president announced the details of the agreement at a news conference Wednesday afternoon.

"We didn't expect this to get as big as it has," said Regis Murayi, one of the black students who was denied entrance and the senior class treasurer. But he said this incident has shown that racial discrimination still happens.

The management of The Original Mothers confirmed there was an agreement and said it was working on a statement. In a previous statement, the club had said that it was conducting an internal investigation and would do a thorough review of its policies and procedures.

"Discrimination against our patrons on the basis of race or ethnicity is not and will not be tolerated," the club said.

The students were on a senior class trip to Chicago when they were denied entrance to the nightclub because of the venue's no "baggy jeans" policy. The club had said it was not an issue of race, but of security with gang activity common in the area.

But the students believed it was a case of racial discrimination. To prove their point, a white student put on the jeans that one of the denied students was wearing and was admitted inside later that same night. The students provided pictures of the two students wearing the same jeans.

The students said their aim was to create a dialogue about racial discrimination — not to receive any monetary award. They noted that they have agreed not to sue the club as part of the agreement.

"Some people suggested we just got in this for the money," Murayi said. "But there was no financial incentive for us. ... This is about the issue of racial discrimination in America."

The incident prompted Washington U. Chancellor Mark Wrighton to send a letter to Chicago Mayor Richard Daley last week asking him to investigate. Wrighton told Daley that he was "deeply disappointed."

University officials said Wednesday afternoon they have not received a response from Daley. But the Chicago Commission on Human Relations did release a statement on Tuesday saying that it is investigating the incident.

Students also had filed complaints with the Illinois attorney general's office and the U.S. Justice Department. U.S. Rep. William Lacy Clay, D-Mo., took up the cause, too, writing a letter to Attorney General Eric Holder asking him for a swift investigation.

The students said they retained a pro bono lawyer so they could respond in kind to the club's lawyer.
