Federal prosecutors in Washington have dropped their case against six Democratic lawmakers who released a video urging military servicemembers to refuse illegal orders.

The decision - confirmed by the BBC’s media partner CBS News - follows US Attorney Jeanine Pirro’s office failing to secure a grand jury indictment against the six military and intelligence veterans.

The justice department could still pursue the case in a different district, but there were no signs on Tuesday that it intended to do so. Pirro’s office had no comment.
