It's Official! - But not just yet

From The Politico:

Fred Thompson's campaign-in-waiting will hold a 4 p.m. conference call today with supporters to brief them on plans for the former Tennessee senator's presidential announcement next week, according to an e-mail obtained by Politico.com.

Randy Enwright, Thompson's political director, said in the message that they will "discuss the next steps as we move forward as an organization." A Thompson aide confirms that they'll share the news about the long-awaited formal launch. "By the end of the day, we'll have more clarity," the aide said, declining to reveal which day the announcement would take place.

UPDATE: Still no official confirmation from the campaign, but Thompson sources now confirm that he will announce his candidacy next Thursday, Sept. 6. The launch will include a tour of Iowa, New Hampshire, South Carolina and Florida. As expected, Thompson will not appear at the GOP debate in New Hampshire on Wednesday, Sept. 5.

A Thompson campaign official says that they'll hold a 4:30 p.m. conference call with the media after briefing supporters about their plans.

If the 4:30 call to the media goes through it will be all over the 'net and cable news within minutes. Look of this (if true) to dominate the Sunday shows.
