Glenn Beck

Professional provocateur Glenn Beck is back at it, this time about the recent Boston Marathon bombings.

Beck, who hosts a syndicated radio show , and previously his Fox News show, addressed the accepted consensus that only two bombers, Tamarin and Dzhokhar Tsarnaev, carried out the terror attacks with no foreign involvement. But Beck theorizes that three bombers may be behind the attack, and Saudi Arabia ties are involved. "The burden of proof is on the federal government, and so far they have not presented one shred of evidence that refutes what The Blaze [network] has reported," Beck said.

The Department of Homeland Security has denied Beck's claims.

Tamarin was killed last week evading authorities, and younger brother Dzhokhar was captured alive. He confessed to his and his brother's involvement in the bombings.
