Holed up with seven other global leaders in the woods of Muskoka, Canada, President Barack Obama gave the White House press corps the slip last night. The president is attending the G-8 and G-20 summits with his global counterparts this weekend. The G-8 began yesterday in Muskoka in Huntsville, Ont., and ends today. The G-20 is in Toronto, about 150 miles away, and starts this afternoon.
