Lance Armstrong 'humbled' by Livestrong charity loss

Disgraced cyclist Lance Armstrong says his most humbling moment during the doping scandal was being asked to step aside from the cancer charity he founded, Livestrong.

In the second half of his interview with Oprah Winfrey, he also said he deserved to be punished but did not think he deserved the "death sentence" of a complete lifetime ban from competitive sports.
