New York: Senator Elizabeth Warren is demanding an investigation into SpaceX after Elon Musk acknowledged he had blocked Ukraine from extending the private Starlink satellite network for an attack on Russian warships near the Crimean coast.

"The Congress needs to investigate what's happened here and whether we have adequate tools to make sure foreign policy is conducted by the government and not by one billionaire," the Massachusetts Democrat said Monday at the Capitol.

Musk, the chief executive officer of SpaceX, is expected to be among the technology industry chiefs to attend a closed-door summit with senators at the Capitol on Wednesday.

Warren, a member of the Armed Services Committee, said she also wants the Defense Department to look into its contractual relationship with the company.

Armed Services Chairman Jack Reed, a Rhode Island Democrat, also said he was concerned about the issue, given that governments traditionally have controlled satellites and presidents decided what to do with them.

He said there have been very positive developments with SpaceX reducing the cost of access to space, including for national security launches, "but he can't be the last word when it comes to national security," he said of Musk.

The Defense Department did not immediately respond to a request for comment on Monday night.

Musk posted on X, his social media network formerly known as Twitter, on Sept. 7 about his decision after a version of the story appeared in a new biography of Musk by Walter Isaacson.

"There was an emergency request from government authorities to activate Starlink all the way to Sevastopol," Musk said. "The obvious intent being to sink most of the Russian fleet at anchor. If I had agreed to their request, then SpaceX would be explicitly complicit in a major act of war and conflict escalation."

Musk later expressed his support for the US: "I am a citizen of the United States and have only that passport. No matter what happens, I will fight for and die in America. The United States Congress has not declared war on Russia. If anyone is treasonous, it is those who call me such."
