"There's a lot of stuff about me on the internet and half of it is totally wrong," Judge Reggie Walton said, "but unfortunately, it's there."
Walton said he is concerned Internet sites, specifically MySpace, which he singled out, could prejudice potential jurors, the Houston Chronicle reported.
"There are some people that are addicted to the Internet," Walton said. "They have to go on the Internet every day and they have to go on the Internet to find out what they heard about. You can't do that."
Clemens is being retried in federal court following a mistrial in which the government charged the former major league pitcher, who starred for Boston, Toronto, Houston and the New York Yankees, with lying to Congress about never using steroids or other performance-enhancing drugs, Newsday said.
Walton told the potential jurors the retrial may last six weeks.
