An audio file of the 911 call made in November by U.S. Sen. Rand Paul, R-Ky., following an altercation with a neighbor that left Paul injured was obtained the Daily News on Monday from the Bowling Green Police Department.

In the call, Paul's breathing seems labored and he asks for police to come investigate the incident. He tells dispatchers that he was assaulted by his neighbor while he was mowing his lawn. (Click here to listen to the call or use the audio player on this page).

Retired physician Rene Boucher, whose arrest following the reported attack Nov. 3 made national headlines, was charged Friday with a federal felony.

U.S. Attorney Josh Minkler of the Southern District of Indiana announced Friday that Boucher, 58, has been charged with assaulting a member of Congress resulting in personal injury, according to a news release.

"Assaulting a member of Congress is an offense we take very seriously," Minkler said in a news release. "Those who choose to commit such an act will be held accountable."

Boucher has signed a plea agreement, although no court date has been set for the taking of his guilty plea and the imposition of any sentence, according to Minkler's office, which was assigned the case after the office of Russell Coleman, U.S. Attorney for the Western District of Kentucky, recused itself.

The federal charge against Boucher carries a maximum penalty of 10 years in prison and a $250,000 fine.

Matt Baker, Boucher's attorney, said he plans to argue for Boucher to be placed on probation.

"He just continues to be sincerely remorseful and he's just very much looking forward to getting this resolved and disposed of and moving forward from there," Baker said.

Baker said that a criminal summons has been issued for Boucher to appear in court, and that his client will voluntarily make an appearance at any date the court assigns in the case.

The Louisville office of the FBI investigated the incident.

Assistant U.S. Attorney Bradley Shepard for the Southern District of Indiana is prosecuting the case as a Special Attorney to the U.S. Attorney General.

Boucher admitted to the assault but denied that it was politically motivated, according to Minkler's office.

Paul, an ophthalmologist and Kentucky's junior senator, reported being attacked Nov. 3 outside his home as he was mowing his yard while wearing headphones.

Boucher was arrested by Kentucky State Police that day and charged with fourth-degree assault, a misdemeanor offense in state court.

He entered a not guilty plea in Warren District Court less than a week later, in what has been his only court appearance on the matter to date.

Boucher, the senator's neighbor in the Rivergreen gated subdivision east of Bowling Green, is alleged to have "had enough" after witnessing Paul stack brush onto a pile near his property, leading him to tackle the legislator, according to court documents.

Jim Skaggs, who developed the subdivision, has said the incident between the two was "strictly a neighborly dispute" that "may have involved a cleanup of leaves issue."

Baker had earlier suggested that property maintenance issues were at the heart of the incident, while members of Paul's staff characterized the incident as a "blindside, violent attack" and denied claims that Paul and Boucher had been involved in a longstanding dispute.

Paul sustained multiple rib fractures and contracted pneumonia, requiring medical attention, according to Minkler's office.
