US watchdog led by Trump ally investigates BBC Panorama edit of January 6 speech

Brendan Carr, head of FCC, asks if programme ever aired in US which is seen as key to any future litigation

A US media regulator led by a close ally of Donald Trump is examining whether an edition of the BBC's Panorama broke US regulations in the way it edited one of the president's speeches.

The Federal Communications Commission (FCC), led by Brendan Carr, has written to the BBC's outgoing director general, Tim Davie, asking whether the programme was ever aired in the US.
