Variety reports that President Bush has asked the networks for a final 15-minute goodbye address this Thursday.

The White House made the request on Monday of the four major broadcast networks: ABC, CBS, Fox and NBC.

Variety's report:

The nets were officially noncommittal as of late Monday, but it seems likely that most, if not all, will grant the request, although some may argue that the address may not be especially newsworthy and will have plenty of coverage on cable and other outlets.

If the address sticks with tradition and goes at 9 p.m. ET, it would preempt or delay in East Coast markets tentpole shows including ABC's "Grey's Anatomy," NBC's "The Office" and CBS' "CSI: Crime Scene Investigation."
