When WCW's properties were purchased by the World Wrestling Federation from AOL Time Warner in March 2001, Robinson was hired by the WWF. He debuted in the WWF as a member of The Alliance, bickering with WWF loyalist referee Jack Doan and accompanying senior WCW official Nick Patrick to ringside for his match at WWF Invasion on July 22, 2001. He refereed his first WWF match on July 2, 2001. Despite being a member of the Alliance, Robinson, unlike fellow Alliance member Nick Patrick, was mostly a fair and impartial referee. An example of this would be the August 20, 2001 episode of "Raw" when he awarded Tajiri a victory over Booker T by disqualification when Booker T started choking Tajiri with his shirt. The night before at Summerslam, Robinson refereed Booker T's match against the Rock and called the match right down the middle as the Rock won the WCW Championship.
