Also, there's been 0 word from Ukraine saying they successfully used Starlink in Crimea prior to this problem.

If it truly was on in the past, they could claim he's lying as they used it successfully.

All we've heard from Ukraine is them condemning the move but nothing backing up it was actively turned off.

Them making a claim would further warrant an investigation.

Given the contradiction, something is probably worth doing ya.

But we are in the alleged territory not admitted territory.

A whole investigation is probably overkill though. I imagine it won't be hard for SpaceX to show their active coverage at a given time and just send the report to congress.

No need for hearings or anything like that.
