Lockheed Martin has been under heightened pressure by the Trump administration. Billionaire Elon Musk, tasked with slashing government costs, has called for ending the F-35 program, describing it as “the worst military value for money in history” and said “manned fighter jets are obsolete in the age of drones.”

Ukrainian President Volodymyr Zelenskyy said Saturday the U.S. has not stopped military aid to Ukraine after newly sworn in U.S. Secretary of State Marco Rubio announced he would pause foreign aid grants for 90 days. Zelenskyy did not clarify whether humanitarian aid had been paused. Ukraine relies on the U.S. for 40% of its military needs.
