US cyclist Lance Armstrong apologises to Livestrong staff

Armstrong made the personal apology during private conversations in Austin, Texas, a foundation spokeswoman said.
His interview with Oprah Winfrey is due to be broadcast on Thursday.
Armstrong, 41, was stripped of his seven Tour de France titles by the sport's governing body last year. He has maintained his innocence, Kazinform has learnt from BBC News.
"He had a private conversation with the staff, who have done the important work of the foundation for many years," Livestrong Foundation spokeswoman Katherine McLane was quoted as saying by Reuters.
"It was a very sincere and heartfelt expression of regret over any stress that they've suffered over the course of the last few years as a result of the media attention," she added.
Armstrong, who also received a lifetime ban from governing body the International Cycling Union (UCI) and the US Anti-Doping Agency (Usada), was reportedly close to tears.
It was not quite a confession of sustained cheating, but that is what many in the cycling world and across America are expecting to hear when they tune in to the cyclist's interview on 17 January, the BBC's Paul Adams in Washington reports.
The recording of the TV interview - his first since being stripped of his wins - took place on Monday.
