NEW YORK – Fox News reporter Geraldo Rivera apologized Sunday for breaking military rules last week when he revealed U.S. troop movements in Iraq.

Military officials denounced Rivera for disclosing unauthorized information after a report in which he squatted in the desert and outlined military movements in the dirt.

In an interview Sunday on Fox, Rivera said he “should have been more careful.”

“Last weekend, after my reports from Iraq with the men and women of the 101st Airborne, I was told I violated one of the rules set up by the Pentagon for reporters embedded with the military,” Rivera said in an interview Sunday on Fox. “My network and I decided it would be best to voluntarily withdraw to Kuwait to review the situation.”

“The review showed that I did indeed break one of the rules related to embedment. I’m sorry that it happened and I assure you that it was inadvertent. Nobody was hurt by what I said. No mission was compromised.”

Rivera wasn’t the only media personality to make headlines last week. Journalist Peter Arnett was dismissed by NBC and National Geographic Explorer for giving an unauthorized interview to Iraqi state television in which he said the U.S.-led war effort initially failed because of Iraq’s resistance. He later took a job for the British tabloid The Daily Mirror.
