Since a former teammate last fall accused Armstrong of cheating to win, of using performance enhancing drugs, speculation has surged that charges would follow. But a decision on whether or not to indict America�s most famed cyclist is not imminent and the federal investigation has encountered serious hurdles, according to lawyers familiar with the matter.
