He apologized in his victory speech. https://www.youtube.com/watch?v=2rHX023p-hk He has to appear before June 7 and will receive a $500 fine and/or 6 months jail time. He will probably plead out and the judge will give him the fine since a report I read said he was a Gianforte backer anyway, good ol' boys network and all. The Congress should censure him.
This just drives home how broken the US justice system is. Multimillionaire assault reporter, gets elected to Congress, has to pay $500 fine. Just sick.
At the least we should go to the Finnish system, where fines like this are based on a percentage of your disposable income, so that the rich can't laugh them off.
