Controversial gospel singer Donnie McClurkin was dropped from performing at a city-sponsored concert which took place on Saturday at the Martin Luther King Jr. Memorial in Washington, D.C.

Mayor Vincent Gray requested McClurkin's withdrawal from the event after gay rights activists criticized his inclusion in the concert.

“The Arts and Humanities Commission and Donnie McClurkin's management decided that it would be best for him to withdraw because the purpose of the event is to bring people together,” a spokesman for Gray told The Washington Post. “Mayor Gray said the purpose of the event is to promote peace and harmony. That is what King was all about.”

But in a video posted online, McClurkin said that he was “bullied” into withdrawing.

“They waited until the last moment to demand that I'm taken off of the concert. Discrimination, bullying it's still a part of this,” McClurkin said in the 7-minute video. “It's bullying, it's discrimination, it's intolerance. And it is depriving someone of their civil rights.”

McClurkin, a Grammy-winning musician who once said that God delivered him from “the curse” of homosexuality, is a prominent figure in the “ex-gay” movement.

“It is intolerant. These are bully tactics, simply because of stances that I took,” McClurkin said in the video. “Never, ever demeaning; never, ever derogatory of any lifestyle. But this is a civil rights infringement situation. And imagine that, in the 21st century, 2013, I, a black man, asked not to attend [inaudible] because of politics.” (The video is embedded on this page. Visit our video library for more videos.)

The concert, the first in a series of events to commemorate the 50th anniversary of the March on Washington, at which King delivered his stirring “I Have a Dream” speech, was titled Reflections on Peace: From Gandhi to King.
