The Associated Press is following their long-standing habit of presenting any news that the White House or its components are claiming executive privilege by presenting it as "obstruction". In an article posted on the Yahoo News site today, Pete Yost intially plays it straight by saying that the Justice Department says the White House Office of Administration is not subject to the Freedom of Information Act (FOIA).
However, Yost then proceeds to quote from no one who might be able to support the Justice Department's claims. Instead, he quotes the Administration spokespeople, then immediately focuses on groups that are hostile to the Administration, such as the Reporters Committee for the Freedom of the Press and the National Security archive. Both of these groups are offered free space to attack the Administration, though no countering information is presented. Both of these groups are clamoring for unfettered release of information that has not been tied to any criminal issues, such as the federal prosecutors' firing, but were strangely silent when it was the Clinton White House claiming executive privilege. I don't recall them pressing for more information regarding Democratic Rep. William Jefferson's bribery issues either, though Jefferson has been caught literally red-handed.
For myself, I do not know whether the Justice Department's claims are meritorious or not. However, for the AP to publish a piece offering only one side of the story is shameless and only provides more evidence that the AP is not providing journalism, but propaganda.
