Attorneys for Bernard Ebbers of WorldCom fame (or infamy) are being permitted by U.S. District Judge Barbara S. Jones, according to the Washington Post (free registration may be required) and other sources, to question the prosecution's star witness about his alleged marital infidelities.
Judge Jones ruled, again according to the Post, that "hearing about Sullivan's alleged infidelity would help jurors determine whether he is truthful and that Ebbers's lawyers are ‘entitled to very wide latitude' when cross-examining the chief witness against him."
