NEW YORK -- Glenn Beck, the man behind today's rally at the site of Martin Luther King Jr.'s famous "I Have a Dream" speech, has built an empire around his own voice that grew exponentially with his move to Fox News Channel and President Barack Obama's election to the White House.
Beck has become a soundtrack for conservative activists and members of the tea party movement, angry and frustrated with Obama and other Democrats. Beck suggests Obama is a socialist moving the country away from its ideals of limited government. Beck's critics contend that he exploits fear with conspiracy theories and overheated rhetoric.
Organizers say the "Restoring Honor" rally isn't about politics. It's to pay tribute to America's military personnel and others "who embody our nation's founding principles of integrity, truth and honor." It also is to promote the Special Operations Warrior Foundation, which provides scholarships and services to family members of military personnel.
The event at the Lincoln Memorial -- where 47 years ago King delivered his speech -- is expected to feature 2008 vice presidential nominee and potential 2012 White House candidate Sarah Palin. Organizers have a permit for up to 300,000 people at the rally, although Beck has said he expects 100,000. Counter-rallies with the Rev. Al Sharpton and others also are planned.
Beck, 46, is a former "morning zoo" radio DJ who cleaned up after years of drug abuse in the 1990s and switched to talk radio. CNN's then-named Headline News network gave Beck his first TV home, and he switched to Fox in January 2009, shortly after Obama was inaugurated.
His Fox show created an immediate sensation, as Beck spun his theories with an emotional fervor that Comedy Central's Stephen Colbert quickly dubbed "crank up the crazy and rip off the knob." MSNBC rival Keith Olbermann likens him to Lonesome Rhodes, the rags-to-riches everyman who spoke to a nation before he was unmasked as a fraud in the 1957 film "A Face in the Crowd."
In interviews, Beck sees himself more as broadcaster Howard Beale, the "mad as hell, and I'm not going to take this anymore" character in the 1976 movie "Network."
His rally has attracted attention and criticism because it is taking place on the anniversary of King's speech and in the same spot. Beck has said it will be the moment when "we reclaim the civil rights movement."
Beck has said he wouldn't have picked the date if he had known about the anniversary. But he rejected attempts to move it, arguing that what he will say is consistent with King's "message of focusing on the content of a person's character above all else." King's niece Alveda King is scheduled to speak.
