Reps. Bart Stupak (D-MI) and Steven LaTourette (R-OH) have written to FCC Chairman Kevin Martin and Assistant Attorney General Thomas Bennett, asking that both organizations deny the proposed satellite radio merger. The letter again references the original 1997 licensing of the satcasters that noted there must be at least two services. The Representatives also say that XM and Sirius are significantly different from terrestrial radio "and other audio technologies, such as iPods."

Stupak and LaTourette conclude that "the Department of Justice and the FCC preserve national radio competition, and safeguard the interests of American consumers by denying this merger."

Last month, 72 members of the House sent a letter to Martin, Attorney General Alberto Gonzales, and Federal Trade Commission Chairman Deborah Platt Majoras opposing the proposed satellite radio merger.
