as of the last week of April, 2006, "snow job" can refer to the lies, distortions and evasive non-answers given to members of the press at daily White House press briefings. (The new WH Press Secretary is Tony Snow, formerly of FOX News.)
When the White House correspondents were told that the president was "concerned" about high gas prices, they knew they were getting the usual Snow Job.
Press: "Hey Tony - why does the President think he's above the law and can do anything he wants to?"
TS: "It's White House policy not to comment on an ongoing investigation."
