With Paul still recovering at his home, U.S. Capital Police have met with Baker to discuss security.
Paul said a final report revealed six broken ribs and a pleural effusion - excess fluid around the lungs - which is worse than the five broken ribs reported Monday from the attack.
Police have charged Paul's neighbor Rene Broucher with misdemeanor assault. "I can't believe he was out of jail the next morning on a 7,500 bail, with such serious injuries". He has not returned multiple calls seeking comment.
Mr. Porter, who says he spoke with Mr. Paul on Saturday after the incident, said the senator told him he and Mr. Boucher had not talked in years. Mr. Baker called them "both prominent members of the medical community" who "worked together when they were both practicing physicians".
"The unfortunate occurrence of November 3 has absolutely nothing to do with either's politics or political agendas". Porter said he was not familiar with any landscaping disputes between the two neighbors. "We sincerely hope that Sen".
Baker said in an interview later, "This is just a profoundly unfortunate set of circumstances that I'm sure that if everyone had it to do over again, it would be done completely differently".
"I'd like to do my due diligence before I'm any more specific", Baker said. Doug Stafford, Paul's senior adviser, called the case a "serious criminal matter involving state and federal authorities". "I am aware of one other recent aggressive interaction with a neighbor who asked Dr. Boucher not to let his dog defecate on the sandy area around our lake".
Rob Porter, who says he has known Paul for 20 years, visited the Senator on Saturday just one day after the attack.
Boucher lives next door to Paul and his wife, according to Warren County property records. Rand Paul does not know why a longtime neighbour tackled him in his yard and broke five of his ribs, sidelining him from the Senate, a close friend of the lawmaker said Tuesday. "It is not clear exactly how soon he will return to work, as the pain is considerable as is the difficulty in getting around, including flying".
Porter said Paul was "in pretty good spirits to be in as much pain as he was".
Baker said Boucher was uninjured.
A prolonged absence by Paul could also complicate matters for Senate Majority Leader Mitch McConnell (R-Ky.) and the broader Senate GOP's legislative agenda.
"I've got a 52 to 48 majority, and as you saw on several occasions, we're not always totally in lockstep", said McConnell. "Anytime we have a senator on our side who's not there, it's potentially a challenge".
