US lawmakers are trying to pressure the Trump administration to release video of a controversial “double-tap” military strike by limiting Defence Secretary Pete Hegseth’s travel budget.

The incident on 2 September, in which the US carried out a second deadly strike on a boat in the Caribbean, has raised fresh questions about the legality of Trump’s campaign targeting alleged drug-carrying vessels.

A provision buried in a lengthy defence spending policy would restrict travel funds for Hegseth’s office until the Pentagon hands over unedited footage. The bill is expected to pass with support from both parties.

US President Donald Trump says release of the video is something for Hegseth to decide.
