Republican apologises to Guardian reporter after winning US House race

Witnesses said he grabbed Ben Jacobs and slammed him to the ground after being asked about the Republican health care bill.

Republican multimillionaire Greg Gianforte has won Montana's only US House seat despite being charged a day earlier with assault after witnesses said he grabbed a Guardian reporter by the neck and threw him to the ground.

Gianforte, a technology entrepreneur, defeated Democrat Rob Quist to continue a two-decade Republican stronghold on the congressional seat.
