A U.S. congressman is asking NBA Commissioner David Stern why the league participated in games with a visiting Greek team that has allegedly breached contracts with former NBA players.

Rep. Peter King, a New York Republican, noted that the Greek club Olympiakos has outstanding U.S. federal court judgments against it. Former NBA player Chris Morris won a judgment against the Greek club, as did his agent, Tom McLaughlin.

King also asks Stern in the letter this week what the league is doing to ensure the fair treatment of American players overseas. The NBA declined to comment on the letter.

Last year, Olympiakos lured former Atlanta Hawks star Josh Childress with a three-year, $20 million deal.
