Here's really all you need to know:
In three separate opinions in the past year, the Government Accountability Office, an investigative arm of Congress that studies the federal government and its expenditures, has held that government-made news segments may constitute improper "covert propaganda" even if their origin is made clear to the television stations. The point, the office said, is whether viewers know the origin. Last month, in its most recent finding, the G.A.O. said federal agencies may not produce prepackaged news reports "that conceal or do not clearly identify for the television viewing audience that the agency was the source of those materials."

On Friday, the Justice Department and the Office of Management and Budget circulated a memorandum instructing all executive branch agencies to ignore the G.A.O. findings. The memorandum said the G.A.O. failed to distinguish between covert propaganda and "purely informational" news segments made by the government. Such informational segments are legal, the memorandum said, whether or not an agency's role in producing them is disclosed to viewers.
Call me a sucker, but earlier I had my doubts about how much all this propaganda stuff was really overseen by the White House itself (as opposed to something more subtle going on, like agency folk simply brown-nosing). Consider me a true believer, b/c the thing is, the OMB is White House central.
