From TalkingPointMemo, this excerpt from AP:

President Bush, again defying Congress, says he has the power to edit the Homeland Security Department’s reports about whether it obeys privacy rules while handling background checks, ID cards and watchlists.

In the law Bush signed Wednesday, Congress stated no one but the privacy officer could alter, delay or prohibit the mandatory annual report on Homeland Security department activities that affect privacy, including complaints.

But Bush, in a signing statement attached to the agency’s 2007 spending bill, said he will interpret that section “in a manner consistent with the President’s constitutional authority to supervise the unitary executive branch.”

Basically, this means he gets to decide whether to report on DHS’s law-abiding or -breaking behavior. Or so he asserts in his extraconstitutional signing statement. More via Yahoo.
