It's All In The Timing

Today the Colombian government made a daring rescue of political prisoner Ingrid Betancourt, three Americans and other hostages from the FARC paramilitary group. John McCain just so happened to be in Colombia at the time. He has one senior advisor, Charlie Black, with longstanding ties to the government, having represented Occidental Petroleum (Colombia's top foreign producer of oil and gas) for many years. Another backer, Carl Lindner, recently pleaded guilty to funding a terrorist group inside Colombia, the AUC (the right-wing paramilitaries who have been fighting the left-wing FARC. Colombia is complicated). Terrorist groups are OK when they're right-wing and in South America, you see.

The point is that McCain's camp has connections with the Colombian government. If they could've moved on this rescue mission a week ago, but could also see an opportunity to please their American masters who they get billions in aid from, and help the national security perception of a trusted friend, I don't see why they wouldn't.
