LOS ANGELES -- An Iraqi man sued two U.S. military contractors Monday, claiming he was repeatedly tortured while being held at the notorious Abu Ghraib prison for more than 10 months.

Also named as a defendant is CACI interrogator Steven Stefanowicz, known as "Big Steve." The suit claims he directed some of the torture.

Phone messages left for Arlington, Va.-based CACI and New York City-based L-3 Communications, formerly Titan Corp., were not immediately returned Monday. There was no phone number listed for Stefanowicz at his Los Angeles address.

The lawsuit, filed in Los Angeles because Stefanowicz lives there, seeks unspecified monetary damages.

NEW ORLEANS -- The way the warden sees it, the more than 400-pound black bear living in the middle of the sprawling Louisiana State Penitentiary is an extra layer of security.

"I love that bear being right where it is," Warden Burl Cain said Monday. "I tell you what, none of our inmates are going to try to get out after dark and wander around when they might run into a big old bear. It's like having another guard at no cost to the taxpayer."

The bear was first seen by an inmate crossing a road in the prison on Friday. It was taking a stroll near the center of the state's only maximum security prison, which is about 115 miles northwest of New Orleans. Most of the roughly 28-square-mile prison is run as a farm, but about 5 1/2 square miles is mostly untouched piney woods.

Prison workers measured the bear's footprints, which were six inches in diameter, Cain said.

"Every inch equals 75 pounds, so that would make it about 450 pounds," Cain said. "The wildlife people told us they think it's a big female they've been tracking for a while."

Prison officials believe they have eight to 10 bears on the grounds, said Gary Young, head of the executive management office at the prison.

COLUMBUS, Ohio -- Risking impeachment, Ohio's attorney general on Monday refused demands from the governor and other fellow Democrats that he resign over a sexual harassment scandal in his office and an affair with a subordinate.

Gov. Ted Strickland told reporters that Democrats will begin drafting an impeachment resolution against Attorney General Marc Dann right away. Republican House Speaker Jon Husted said Monday that his chamber -- which takes the first step in any impeachment -- was already reviewing the process.

Virtually every state-level Democratic officeholder urged Dann to resign in a letter late Sunday after Strickland tried twice during the day to persuade him to leave office.

A sexual harassment investigation uncovered an atmosphere in Dann's office rife with inappropriate staff-subordinate relationships, heavy drinking, and harassing and threatening behavior by a supervisor. On Friday, Dann admitted to an extramarital affair with a subordinate after the investigation threatened to reveal the relationship.

Increased breast-feeding during the first months of life appears to raise a child's verbal IQ, according to a study of nearly 14,000 children released Monday.

The study in Archives of General Psychiatry found that 6-year-olds whose mothers were part of a program that encouraged them to breast-feed had a verbal IQ that was 7.5 points higher that children in a control group.

The researchers said their findings suggested that the longer an infant is fed exclusively breast milk, the greater the IQ improvement.

The results echo smaller previous studies that found children and adults who were breast-fed tend to have higher IQs than whose who were not.

Lead author Dr. Michael Kramer, a professor of pediatrics at McGill University in Montreal, said the IQ improvements were modest and might not be noticeable on an individual basis. But he added that the increase could have a significant effect on society as a whole.

"We're not talking about making a child who has trouble in school and is dropping out into a genius," he said. "But if we can increase IQ by three to four points in the whole population we can have fewer children at the low end and more Einsteins at the high end."

DENVER -- With the Beijing Games less than 100 days away, the International Olympic Committee clarified its protest rules Monday, saying that athletes' external appearance, clothing and gestures would be scrutinized in China.

The IOC sent a six-point letter, a copy of which was obtained by The Associated Press, to the national Olympic federations in response to their request for interpretations of Rule 51.3 of the Olympic charter. That rule states "no kind of demonstration or political, religious or racial propaganda is permitted in any Olympic sites, venues or other areas."

The letter expanded on the rule, saying: "The conduct of participants at all sites, areas and venues includes all actions, reactions, attitudes or manifestations of any kind by a person or group of persons, including but not limited to their look, external appearance, clothing, gestures, and written or oral statements.

"As in all Olympic Games, such conduct must also, of course, comply with the laws of the host state."

The IOC has long relied on Rule 51.3 as its guiding principle for Olympic participants, but has been pressed of late to offer more guidance in light of recent protests over Tibet and China's crackdown on dissenters.

Last month, IOC president Jacques Rogge said IOC officials will use common sense to decide whether athletes are simply celebrating victories or using them to make political statements.
