One of the things that I've seen since Shrub took office is a slavering devotion to the White House version of reality. Bush has gotten a pass on dozens of issues that, had they taken place under Clinton, would've led to congressional hearings and unhinged conspiracy theories.
The Washington Post made an alteration to a News Story. You know that stuff happens, particularly since one of the carrot/sticks held over every media outlet in the US is the fact that those outlets that don't play nice won't be granted any kind of access to senior administration officials. That's the GWB White House tactic, and I'm sure this is just business as usual. The only difference in this case is that someone noticed the change.
Of course, if you're a gay escort pretending to act as a journalist for an administration-friendly publication, even though you don't have proper credentials to even attend press briefings, the rules are a little different...
