Yesterday:

I am scheduled to leave tomorrow for a long-planned trip to five African nations. Moments ago, my staff informed the House leadership that I’m prepared to delay my departure, and stay in Washington with them, if it will help them complete their work on this critical bill.

(emphasis added)

Today:

President Bush leaves Washington tonight on a six-day trip to Africa. It’s his second tour of the continent since becoming president and he intends to use it to underscore how the U.S. is helping Africa achieve progress against war, disease and poverty.

So is he of no help (ie: not significant), or did he lie again?
