As people like our own Rick Moran dig up more and more of the Barack links to Rezko, others are uncovering more and more links between Barack and other unsavory characters like  ex-weatherman and terrorist defender Ayres.Today's report involves Obama's connections with Columbia University's Professor Khalidi and pro Palestinian groups ,including the PLO:

Democratic presidential frontrunner Sen. Barack Obama served as a paid director on the board of a nonprofit organization that granted funding to a controversial Arab group that mourns the establishment of Israel as a "catastrophe." (Obama has also reportedly spoken at fundraisers for Palestinians living in what the United Nations terms refugee camps.)

The co-founder of the Arab group, Columbia University professor Rashid Khalidi, is a harsh critic of Israel who reportedly worked on behalf of the Palestine Liberation Organization when it was labeled a terror group by the State Department.

Khalidi held a fundraiser in 2000 for Obama's failed bid for a seat in the U.S. House of Representatives.
