Sen. Rand Paul announced that he will likely be absent from the Senate until September after having part of his lung removed following an attack by his neighbor.

“Unfortunately, I will have to limit my August activities. Part of my lung damaged by the 2017 assault had to be removed by surgery this weekend,” Paul tweeted Monday morning.

The Kentucky Republican underwent the procedure at Vanderbilt University Medical Center in Nashville, Tennessee. In the tweet, he praised the “great” doctors, nurses and hospital staff.

Paul was assaulted at his home in Bowling Green, Kentucky, in November 2017 by Rene Boucher, a neighbor in his gated community.

The senator suffered six broken ribs and bruised lungs as a result of the attack, which allegedly began over a landscaping dispute, and underwent hernia surgery in January for injuries related to the incident.

Boucher was hit with felony assault charges following the incident and served 30 days behind bars after pleading guilty. He had faced up to 10 years.

He also was ordered to pay over $580,000 in damages as part of a civil suit brought by Paul.

Paul isn’t the only Kentucky senator in need of medical attention this weekend.

Senate Majority Leader Mitch McConnell (R-Ky.) fractured his shoulder Sunday after falling on his outdoor patio at his Louisville residence.

McConnell was treated for his injuries and plans to work from home while he recovers.
