Montana Republican congressional candidate Greg Gianforte allegedly assaulted a reporter at a campaign event in Bozeman on Wednesday evening, one day before voters go to the polls to fill the seat vacated in March by Interior Secretary Ryan Zinke. The reporter, Ben Jacobs of the Guardian, had previously broken a major story about Gianforte's investments in Russian companies.
