WASHINGTON-- Montana Republican Greg Gianforte was sworn in on Wednesday as the newest member of Congress, a month after he body-slammed a reporter who had questioned him about the GOP health care bill.

Gianforte, a wealthy former software executive, has called for civility in politics following his conviction for assaulting the reporter the day before winning a special congressional election.

Gianforte, 56, won a May 25 special election to serve the 18 months remaining in the House term vacated by now-Interior Secretary Ryan Zinke. Gianforte, who already has filed for re-election, was to take the oath of office by House Speaker Paul Ryan, R-Wis.

In brief remarks, Gianforte said he was "humbled and honored."

Majority Leader Kevin McCarthy, R-Calif., said Gianforte was "a do-er, we're happy to have him here."

With Gianforte in the House, Republicans have 239 members to 193 for Democrats. Winners of three elections will be sworn in at later dates.

Gianforte told The Associated Press last week that he is keenly aware he will carry with him the distinction of being the congressman who beat up the reporter.

"I can't erase it, but I did do everything in my power once the event was over to take responsibility," he said.

Members of Congress have an obligation to ratchet down the vitriol in politics, especially after last week's shooting of House Majority Whip Steve Scalise during a Republican congressional baseball practice, Gianforte said. The shooter had volunteered for Bernie Sanders' Democratic presidential campaign and expressed grievances online about President Donald Trump and Republicans.

"I believe that good things can come out of bad," Gianforte said. "It's important to make sure we reach out to all parties and hear their voice. I think the other parties have an obligation, as well, to be respectful and in that dialogue."

Guardian reporter Ben Jacobs said Gianforte body-slammed him to the ground and broke his glasses after Jacobs asked about the health care bill that had recently passed the Republican-controlled House. Audio taken by Jacobs recorded the sounds of a scuffle followed by Gianforte yelling, "Get the hell out of here!"

Gianforte was ordered to pay a fine, perform community service and take anger management training, but he received no jail time. He also avoided a civil lawsuit by writing a letter of apology to Jacobs and donating $50,000 to the Committee to Protect Journalists.

In a statement Wednesday, Jacobs said he welcomed Gianforte to Capitol Hill, "where I'm confident he will live up to his pledge to champion a free press and the First Amendment. In the courtroom last week, he openly offered to do an interview with me when he came to Washington and I look forward to taking him up on that in the coming days."
