Gianforte was convicted in June and argued earlier that the court lacked authority to order the fingerprinting and mugshot of the congressman since he was charged with a misdemeanor rather than a felony. There is no record however of his objecting to the belated release of the mugshot sought by the media.
As mugshots go, this is a remarkably good shot for the congressman. If you know that a mugshot is likely to appear throughout your next campaign, you might as well make it presentable.
