Cycling: Armstrong legal team demands apology

Attorneys for Lance Armstrong have demanded an on-air apology from 60 Minutes after the head of Switzerland's anti-doping lab denied allegations he tested positive for performance-enhancing drugs at the 2001 Tour de Suisse.

In a letter sent to CBS News chairman and 60 Minutes executive producer Jeff Fager, lawyer Elliot Peters said the May 22 segment about Armstrong was built on a series of falsehoods.
