A growing number of U.S. lawmakers are raising questions about the potential for SpaceX CEO Elon Musk to interfere or take over a $2.4 billion Federal Aviation Administration telecommunications contract with rival Verizon.

Elon Musk’s promotion of his satellite company's services came as his Department of Government Efficiency weighs potentially steep cuts at the FAA, which is overseeing the contract.

The FAA is testing Elon Musk's Starlink satellite internet service. That could raise a possible conflict of interest, experts say.
