Oprah lets Lance interview stand After landing a doping confession from embattled cyclist Lance Armstrong, Oprah Winfrey has a message to her critics. "I shall let the work speak for itself," Ms. Winfrey told The Globe on Monday when asked about those who say she took it easy on the seven-time Tour de France winner. She spoke briefly before taking the stage in Edmonton to start a Western Canada mini-tour that comes amid buzz about her interview with Mr. Armstrong last week. Mr. Armstrong, 41, confessed to "one big lie," acknowledging after years of denial that he'd used performance-enhancing drugs throughout much of his career. "All the fault, and all the blame here, falls on me," the cyclist and cancer survivor told Ms. Winfrey. Some praised the talk show icon's strategy - in particular, drawing out a confession in the first minute. Others think Mr. Armstrong got off easy. Armstrong critic and journalist Paul Kimmage told the Irish Independent Ms. Winfrey "dropped the ball" and failed to press Mr. Armstrong on key points. Globe and Mail columnist Bruce Dowbiggin wrote that Ms. Winfrey's "scatter-shot approach repeatedly let Armstrong off the hook." Ms. Winfrey simply let the interview stand, declining further comment on Monday. On stage, she joked to the audience her planned diet was interrupted because "Lance called." "I was cramming for a solid week just to learn everything I could about cycling," she said, before poking fun at the city's winter climate. "I will say this: What was I thinking?" she told the crowd. Why didn't you tell me to come in the spring or fall? Outside her hotel earlier, she'd complained the city was "colder than Siberia," as temperatures hovered around -13 Celsius. Ms. Winfrey's three-city tour continues in Calgary on Tuesday and Vancouver on Thursday.
