The reporter whom Montana Rep. Greg Gianforte body slammed in May said Tuesday that the Republican congressman is refusing to give him the on-the-record interview that Gianforte promised.

In a statement the Guardian's Ben Jacobs tweeted, the reporter wrote, "In refusing to do the promised on-the-record interview with me, Congressman Gianforte continues his pattern of avoiding responsibility for his actions and refusing to live up to the statements made in what I had thought was a sincere apology."

In a sentencing hearing, Gianforte told Jacobs, "If and when you’re ready, I look forward to sitting down with you," The Washington Post reported. Gianforte's communications director Travis Hall also told the Post that he had been in contact with Jacobs to schedule a "meeting."

"We’ve offered times to Ben to sit down with Greg when the House reconvenes after the district work period," Hall said. According to the Post, Hall's statement did not indicate whether Gianforte intended for the meeting to be "on the record."

Jacobs also claimed Tuesday that Gianforte had slandered him and tried to avoid pleading guilty to the attack, but added that he could "take some minor consolation that in the past two months, his efforts to avoid answering any questions from me have been non-violent."

After Jacobs questioned him on health care on the eve of his special election to the U.S. House of Representatives, Gianforte body slammed Jacobs and broke his glasses, the reporter tweeted just after the assault occurred. The incident gained national attention and sparked backlash against Gianforte, who won the election despite the assault.

Gianforte later apologized and pledged to donate $50,000 to the non-profit Committee to Protect Journalists. Gianforte pleaded guilty to a misdemeanor charge in June, and The Daily Chronicle reported he must complete 40 hours of community service, pay $385 in fines and fees, and undergo 20 hours of anger management.
