Several Democratic lawmakers are calling for answers after concerns were raised by families of sailors aboard USS Abraham Lincoln about the deteriorating living conditions and worsening mental health during the ship’s record-breaking deployment amid the war with Iran.

Since the Lincoln left its home port of San Diego last November, the aircraft carrier has been deployed for more than 250 days after being redirected to the Middle East to support US operations in the war with Iran, now entering its sixth month. With more than 5,000 sailors and Marines aboard, it has not made a port call in more than 200 days, setting a modern-day record for consecutive days at sea, according to Sen. Richard Blumenthal.

News outlets Stars and Stripes and the Navy Times reported this week that there had been multiple attempts by crew members to jump overboard, citing interviews with sailors and families of those on board who described the impacts of the lengthy deployment.
