Last week, Boucher, 59, admitted before a judge that he had entered Paul's property and had tackled him from behind although he pleaded "not guilty" to the charge of assault, which could carry a penalty of a year behind bars and a $500 fine.
Via Twitter, Paul thanked people for their support during his recovery and said he was returning to work Monday and looking forward to helping pass the GOP's tax reform plan. A pretrial hearing was set for November 30.
Paul previously said on Twitter he suffered the broken ribs from the November 3 incident and that X-rays showed a pleural effusion, which is a buildup of fluid in the tissues that line the lungs and the chest.
The lawyer for Paul's neighbor/assailant, Rene Boucher, denies that the attack was politically motivated, and instead said that it stemmed from a "landscaping dispute". Paul could not be reached by Reuters Monday. "We've never had words over anything, we've never had a dispute or discussion or word".
The Kentucky State Police and the Federal Bureau of Investigation are investigating the incident, according to Warren County Attorney Amy Milliken.
"From my perspective, I'm not really too concerned about what someone's motive is", Paul told the Washington Examiner.
