NBA commissioner Adam Silver announced Tuesday that L.A. Clippers owner Donald Sterling would be fined $2.5 million and banned from the league for life after recordings of him making racist remarks were revealed via online media outlets this past weekend. Silver announced Sterling’s penalty—the maximum available under league bylaws—following an investigation headed up by Wachtell, Lipton, Rosen & Katz partner David Anders, which authenticated the recordings.

Celebrity gossip website TMZ posted audio online late Friday night capturing Sterling telling a girlfriend that he didn’t want her posting pictures of herself with African-Americans on social media or bringing black people to Clippers games.
