UPDATE: Senator Paul recovering from assault, Boucher's attorney comments on client

A Senior Advisor to Senator Rand Paul says he has suffered five fractured ribs after an assault on Friday.

Officials tell 13 News that Senator Paul is at his home in Bowling Green recovering from those injuries. They're not sure at this time -- due to the extent of those injuries -- when he'll be able to return to work.

Senator Paul has sent out tweets thanking the public for their thoughts and well wishes.

Kentucky State Police charged Senator Paul's neighbor, Dr. Rene Boucher with the assault on Friday.

Troopers say they discovered that Boucher intentionally assaulted Senator Paul.

Boucher has since been released from the Warren County Regional Jail.

Matthew Baker, Boucher's attorney, spoke with 13 News over the phone about what led up to the incident.

"Senator Paul and Rene Boucher have lived next door to each other for years," says Baker.

KSP says the FBI is investigating to make sure the assault wasn't politically motivated. According to Baker, politics had nothing to do with it.

"It was absolutely not planned out before-hand. I've seen a couple of media spots that would tend to suggest that it was politically motivated. That is absolutely and unequivocally untrue," he adds.

Baker goes on to say, "It's just a disagreement -- a long standing disagreement between two neighbors."

According to Senator Paul's Senior Advisor, Paul's injuries could take weeks to months to fully recover.

We spoke with Kentucky State Police on Monday, and troopers say the investigation is still ongoing.

KSP says once it's finished they'll send everything over to the Commonwealth Attorney's Office and the Warren County Attorney's Office for review.

Boucher is expected to make his first court appearance at the Warren County Justice Center on Thursday.

Baker says this was a "hugely regrettable incident" and he and his client are hopeful to make amends and put this behind them as soon as possible.
