The Senate Armed Services Committee is probing national-security issues raised by Elon Musk’s decision not to extend the private Starlink satellite network to aid a Ukrainian attack on Russian warships near the Crimean coast.

Chairman Jack Reed said in a statement Thursday the reports on the use of Starlink exposed “serious national-security liability issues and the committee is engaged on this issue.”

“The committee is aggressively probing this issue from every angle,” he said.

A trio of Democratic senators sent a letter to Defense Secretary Lloyd Austin on Friday over concerns that tech billionaire Elon Musk may have personally impacted the war in Ukraine and by extension, U.S. foreign policy.

Musk confirmed earlier this month that he refused access to his Starlink satellite internet service to the Ukrainian military when they wanted to use it for an offensive operation in Crimea last year.

Sen. Elizabeth Warren, D-Mass., has called for a Senate inquiry into the alleged involvement of tech magnate Elon Musk in obstructing a Ukrainian drone's attempt to target Russia's naval fleet in the Black Sea last year.

"We need to investigate how this happened. What's in those contracts that permits him to have this kind of power?" Warren, a member of the Senate Armed Services Committee and its subcommittee on emerging threats and capabilities, told reporters during a Capitol Hill forum dedicated to discussions about artificial intelligence.
