Fox News senior national correspondent William La Jeunesse discusses the shocking video of a grandfather being thrown 8 feet into the air by a wild bison at Yellowstone National Park on 'The Faulkner Focus.'

A shocking video from Yellowstone National Park captures a massive bison attacking a tourist, flipping him 8 feet into the air. The man, walking with his grandson, sustained broken bones but is reportedly in good spirits. Wildlife experts advise visitors to maintain at least a 25-yard distance from bison, which can weigh over 2,000 pounds and run at 35 mph, especially during mating season.
