Democratic senators Jeanne Shaheen and Chris Coons are pressing Elon Musk to keep all records about SpaceX's Starlink and Starshield satellite restrictions in Ukraine.
Starshield is a lifeline for Ukrainian military communications during the war with Russia, so lawmakers are worried about one company having so much control over such critical tech.
Requests cover Musk SpaceX US talks
The senators want details from September 1 onward (covering talks between Musk, SpaceX, and US officials) after reports that Starlink and Starshield restrictions were hurting Ukraine's military efforts.
Even though some services came back online by late October, Ukraine's president says communication problems continue.
The whole situation has sparked fresh debate over how much power private companies should have in global conflicts.
