The speech is tonight, the surge has already begun

Well, while we all sit and watch Mr. Bush talk about the surge tonight, new troops are getting used to life in Baghdad. I guess that's why the talking points were leaked; the surge began while we were all talking about the President talking about a surge.

President Bush's speech may be scheduled for tonight, but the troop surge in Iraq is already under way.

ABC News has learned that the "surge" Bush is expected to announce in a prime time speech tonight has already begun. Ninety advance troops from the 82nd Airborne Division arrived in Baghdad today. An additional battalion of roughly 800 troops from the same division are expected to arrive in Baghdad Thursday.

It is the first small wave of troops in a new White House strategy that is expected to put more than 20,000 additional U.S. troops on the ground in Iraq and likely require new call-ups of the National Guard.

The president is expected to deliver his announcement about the increase of troops, a plan that has already been met with stiff criticism from many members of Congress, in a speech tonight from the White House.

The arrival of additional forces in Iraq comes a day after leading Democrats said they would back legislation that would block funding to pay for the additional military forces.
