A collection of press freedom groups has filed a congressional ethics complaint against Rep.-elect Greg Gianforte, R-Mont., for allegedly body-slamming a reporter asking him a question.

The groups PEN America, Free Press, Society of Professional Journalists and Reporters Without Borders filed a formal complaint with Congressional ethics officials on Friday. The complaint comes about a week after Gianforte allegedly body-slammed Guardian reporter Ben Jacobs, who was asking him a question about the recent Congressional Budget Office estimate of the GOP’s health bill.
