Jose Diaz-Balart — the Brian Williams of Telemundo — is doing double duty on two NBCU networks this week. He’ll anchor his nightly newscast “Noticiero Telemundo” at 6:30pmET as well as filling in for Contessa Brewer on the NoonET hour on MSNBC. This makes Diaz-Balart the first journalist on U.S. television to anchor both an English and a Spanish-language newscast on two networks for a week straight. The lead story on his first MSNBC show on Monday was the Casey Anthony trial which is being covered by correspondent Lilia Luciano, who was hired away from Univision in October. Luciano is covering the trial for NBC News and Telemundo.
