Presumptive Republican presidential nominee John McCain attended an economic forum in Aspen Thursday where he chastised Congress for going on recess "while people are paying $3.75 a gallon for gas." The audience of 800 began hooting and laughing and yelled that in Aspen they're paying nearly $5 a gallon. McCain recovered with a well-received crack about plans to "soak the rich." The Arizona senator made the comments at the Aspen Institute after a noon fund-raiser.He also recycled at least one of the same jokes he used in his speech at the Aspen Institute last year, when he noted that Arizona is so dry that the trees chase the dogs.He also called Russias military action in neighboring Georgia. "an act of aggression, and "the biggest crisis since the end of the Cold War." McCain has no scheduled public events Friday but is expected to meet with top aides. Campaign sources said McCain is likely to spend a few days next week huddled with advisers, possibly working on his vice presidential decision.
