US Senators Elizabeth Warren, Mitt Romney, Dianne Feinstein, Ted Cruz, Roger Wicker and Richard Blumenthal called for the FAA to temporarily ground all 737 MAX 8 jets.[1][2][3] Ted Cruz and Roger Wicker announced their plans to hold a hearing at the United States Senate Commerce Subcommittee on Aviation Operations, Safety, and Security "to investigate these crashes, determine their contributing factors, and ensure that the United States aviation industry remains the safest in the world."[66] Elizabeth Warren accused the Trump administration of protecting Boeing, saying: "The Boeing 737 MAX 8 is a major driver of Boeing profits. In the coming weeks and months, Congress should hold hearings on whether an administration that famously refused to stand up to Saudi Arabia to protect Boeing arms sales has once again put lives at risk for the same reason."[4]
