Video undermines US Olympic swimmers' 'mugging' story

Allegations that star US swimmer Ryan Lochte invented a story about him and three team mates being mugged at gunpoint in Rio strengthened Thursday with video footage showing them in a gas station altercation. The controversy took a dramatic new twist after the leaking of security camera footage from a gas station on Brazil's Globo television. This came hours after two of the swimmers were hauled off a plane about to leave Rio de Janeiro for the United States and taken in for questioning.
