At the center of the ring of "peace activists" is a guy by the name of Hatem Abudayyeh, a left wing activist and Executive Director of the Arab American Action Network. I'm getting tons of emails about this, but Jim Hoft has a good summary of the link between the "charity" run by Abudayyeh suspected of supporting terror, and President Obama:
The Arab American Action Network was founded by former PLO operative and close Obama family friend Rashid Khalidi. Obama was a director of the Woods Fund from 1994 through 2001, when the board approved a $40,000 grant to the Arab American Action Network.
In 2003 Barack Obama was an honored guest at a dinner sponsored by the AAAN for former PLO-operative Rashid Khalidi.
Ah, so that's what he meant by "community activist"!
