The U.S. military says the Asia-based USS George Washington aircraft carrier is now operating in the Middle East. The ship is relieving the long-deployed USS Abraham Lincoln following reports of mental health challenges and supply shortages aboard while it was supporting the Iran war. The Lincoln's deployment has included a record-setting uninterrupted time at sea of more than 250 days. It's not clear when the USS Abraham Lincoln will return to the U.S., but it takes just over a month to get back. Several Democratic lawmakers are pressing for accountability over the conditions aboard, which Defense Secretary Pete Hegseth has said were misrepresented.
