The USS Abraham Lincoln and its crew of 5,000 sailors are on their way back to the US after a nine-month deployment to the Middle East, supporting America's operations against Iran. In recent weeks, the aircraft carrier has been plagued by reports of low morale on board, with sailors reportedly not having a day off. Democratic Senators raised concerns about poor living conditions, including shortages of basic supplies and water contamination, after Iran destroyed a vital supply hub in Bahrain. The Abraham Lincoln will now embark on its return journey to San Diego, which can take several weeks. USS George Washington is now in the Middle East in its place.
