Transcript for Rand Paul's neighbor pleads not guilty to attack
This morning we're learning more about what may have sparked that encounter between senate Rand Paul and his neighbor that left the senator with six broken ribs. Steve osunsami is in bowling green with new reporting. Good morning, Steve. Reporter: Good morning to you, Michael. Politically these two men couldn't be further apart and friends of the senator believe that's why his neighbor lost it but homeowners we talked with say this argument was probably over something much more simple. Commonwealth versus Rene Boucher. Reporter: Dr. Rene Boucher, U.S. Senator Rand Paul's neighbor seen in court is out on bond this morning ordered to stay at least 200 feet away from the lawmaker. Yes, sir. Reporter: He is accused of attacking the senator last Friday and breaking six of the senator's ribs. He is pleading not guilty but police say he's already admitted to tackling his famous neighbor. People who live here tell us what happened in the grass between their homes can be summed up in two word, yard rage. Paul is famous for mowing his own lawn and posting pictures to prove it and he's equally famous according to some neighbors for not bagging all his leaves. I mean, they had a big spat, quarreling and that would not have surprised me. Reporter: Jim Skaggs built this exclusive gated community in Kentucky and says the two men have argued about their lawns over the years. It sounds like you believe this is more about leaves and tree limbs than about politics. It would seem to me that would make more sense. It really doesn't make a lot of sense at all. That you would be this violent over a leaf. Reporter: The retired anesthesiologist had at one point been trying to sell his home and move to Florida. These are pictures from one of the listings. He could now spend up to a year in jail if convicted. They got into a disagreement and it ultimately resulted in my client being charged with fourth degree assault. I can assure you that he wished it never had happened. Reporter: Just to underline these two men are doctors and this could get more serious. The FBI is now talking to both the senator and local authorities. There is the possibility here of federal charges.
