The veteran Democratic Senator, from Vermont, tweeted criticism for the department on Sunday, claiming it had managed to ‘lose track of billions’

"Elon Musk is right. The Pentagon, with a budget of $886 billion, just failed its 7th audit in a row," he said. "It’s lost track of billions. Last year, only 13 senators voted against the Military Industrial Complex and a defense budget full of waste and fraud. That must change."
