Kentucky Senator Rand Paul’s injuries are more serious than previously reported, following an attack, allegedly by one of his neighbors, last week in Bowling Green, KY.

“A medical update: final report indicates six broken ribs & new X-ray shows a pleural effusion‬,” tweeted the Republican senator Wednesday.

Pleural effusion is a buildup of fluid around the lungs.

Previous medical reports stated that Paul suffered five broken ribs and lacerations to his lungs. Reports indicate a violent attack from Paul’s long-time neighbor, 59-year-old retired doctor Rene Boucher, after a dispute. The exact nature of the dispute remains unclear, but Boucher’s lawyer claimed it had nothing to do with politics.

Police arrested Boucher and charged him with fourth-degree assault.
