Rand Paul's attacker pleads guilty in federal court. Here's how long he will likely go to prison.

The man who assaulted Sen. Rand Paul (R-Ky.) last November, leaving him with serious injuries including six broken ribs, pleaded guilty to assault charges in court on Friday.

What happened?

Rene Boucher, Paul's 59-year-old anesthesiologist neighbor, pleaded guilty to a felony charge of assaulting a member of Congress resulting in personal injury. Boucher entered his plea during a "brief hearing" at a federal courthouse in Kentucky, according to the Washington Post. He had previously pleaded not guilty last November.

Boucher will have to wait until June 15 to learn his sentence.

The conviction carries a maximum sentence of 10 years in federal prison and a fine up to $250,000, but Boucher won't likely see the maximum sentence after his attorney reached a plea deal in January.

In exchange for Boucher's guilty plea, prosecutors will only seek a 21-month sentence, according to Fox News. Still, Boucher's attorney, Matthew Baker, is hoping the judge only sentences his client to probation.

What did Boucher's attorney say?

Baker told Fox News on Friday that Boucher is "relieved" to move on to the sentencing phase of the case. He also maintained his claim that Boucher's attack was in no way, shape or form politically motivated, but instead over a landscaping dispute.

He said:

He is looking forward to obtaining a complete resolution.

This whole situation had absolutely nothing to do with anyone's politics or political agendas or political parties. It has been a longstanding dispute between two neighboring property owners over the issue of their property maintenance of lack thereof.
