Federal attorneys have subpoenaed The Times-Picayune's parent company for information about 11 commenters on the newspaper's website, as part of an investigation of posts there by two federal prosecutors.
The newspaper reports that company attorneys have objected thus far to providing the information, asking the government to explain why it's wanted.
The Justice Department has filed two criminal misdemeanor charges against Temple-Inland, the former owner of a paper mill in Bogalusa, for violating federal environmental laws.
The charges stem from a five-day spill of pollutants from the company's paper plant into the Pearl River in August 2011.
A bill of information filed in U.S. District Court in New Orleans on Dec. 20 says a "liquor" produced during the processing of pulpwood into paper pulp was discharged, resulting in the death of thousands of fish.
A federal prosecutor demoted for anonymously posting comments on a newspaper's website has retired.
A Justice Department spokesman said Monday that Jan Mann and her husband, fellow prosecutor Jim Mann, both retired from the U.S. attorney's office in New Orleans.
Jan Mann was former U.S. Attorney Jim Letten's top assistant before he demoted her last month. Letten resigned earlier this month amid a Justice Department probe of comments that she and another prosecutor, Sal Perricone, posted on Nola.com, The Times-Picayune's companion website.
