AUSTIN (November 12, 2012)—Texan Lance Armstrong has cut formal ties with his cancer-fighting charity to avoid further damage from the doping charges that cost him his seven Tour de France titles.

Armstrong resigned from the board of directors for Livestrong on Nov. 4 after resigning in October as chairman of the charity he founded.]

The U.S. Anti-Doping Agency ordered Armstrong banned from the sport for life and stripped of his titles.

The International Cycling Union, which had originally supported Armstrong's fight, later agreed to wipe out Armstrong's record seven victories.

Livestrong spokeswoman Katherine McLane said Monday that Armstrong "remains the inspiration," and is still its largest donor, having contributed nearly $7 million over the years.
