The Washington Post reports a Navy commander accused of trading military secrets for cash bribes, plane tickets, flings with prostitutes and Lady Gaga concert tickets pleaded guilty Thursday to corruption charges in federal court in San Diego. Cmdr. Michael Misiewicz, 48, a graduate of the Naval Academy in Annapolis, became the eighth person to plead guilty in a gigantic corruption case that has rocked the Navy and reached high into the officer corps. More than 100 people remain under investigation for possible criminal, ethical or administrative violations. Misiewicz had contested the charges against him after he was arrested in September 2013 but he agreed to change his plea and appear before a judge late Thursday.
