(Portland, OR)  --  Portland Trail Blazers owner Paul Allen says racist comments attributed to Los Angeles Clippers owner Donald Sterling are "abhorrent."  Allen says the statements, if true, are "not acceptable for the owner of an NBA franchise or anyone in professional sports."  Sterling is under fire after a recording containing comments he allegedly made surfaced.  The recording includes the voice of someone who is said to be Sterling, telling his girlfriend not to bring black people to games.
