of course he will!

Bush will veto House bill on Iraq withdrawal. Talking to reporters aboard Air Force One, White House adviser Dan Bartlett said that the White House plans to veto the the House Democrats’ bill to withdraw troops from Iraq by the fall of 2008. He said, “It would unnecessarily handcuff our generals on the ground. … Obviously, the administration would vehemently oppose and ultimately veto any legislation that looks like what was described today.”
