Washington (CNN) - The Rev. Al Sharpton and a range of activists on Saturday fervently marked the 47th anniversary of Martin Luther King, Jr.'s "I Have a Dream" speech and some delivered pointed remarks about conservatives rallying nearby at the site where King delivered his seminal address.
Sharpton spearheaded the "Reclaim the Dream" rally at Dunbar High School in northwestern Washington, addressing a throng that later embarked on a march to the planned King memorial after they listened to speaker after speaker extol the virtues and visions King stood for.
Sharpton and others couldn't resist discussing the controversial event at the Lincoln Memorial organized by conservative talk show host Glenn Beck, a rally Beck called "Restoring Honor." Beck, who has a program on Fox News as well as several radio programs, was criticized for holding his rally at the site of King's speech on the anniversary.
"They may have the mall," Sharpton said, "but we have the message. They may have the platform but we have the dream."
