John Fund has this article in the WSJ on the NPR defunding vote and George Soros's support for NPR.  The article includes this gem from the O'Keefe video:

[NPR's director of institutional giving] also noted that Mr. Soros's foundation first contributed to NPR in 2000 and that some of the money went to fund a documentary critical of the death penalty as it's employed in Texas. It aired on October 12, 2000, a day after then-Texas Governor George W. Bush was questioned about the death penalty in a debate with Democratic candidate Al Gore.
