Michael Mukasey, who served as attorney general under former President George W. Bush, is arguing against a bill pending in the U.S. Senate that would allow reporters to protect their confidential sources in most instances, The Wall Street Journal reports. Mukasey argues the bill is '"fraught with near-meaningless amibiguity'" on who would be covered journalists and that the bill would give judges too much power to decide "whether the disclosure of the information would be contrary to the public interest and thus not protected," The Journal also reports.
