Sen. Rand Paul has returned to Washington following an attack in his yard that left him with six broken ribs.
Paul entered the chamber, hands by his sides, to cast a vote Monday night. He chatted briefly with other senators, including Democratic Sen. Brian Schatz of Hawaii.
Paul posted a message on his Twitter account earlier Monday saying he is returning to work in the Senate despite being in a good deal of pain.
Paul was attacked Nov. 3 while mowing his lawn. Police have charged Rene Boucher with misdemeanor assault. Boucher pleaded not guilty during a court hearing last week.
Boucher and Paul have been neighbors for 17 years. Boucher's attorney said the attack was motivated by a trivial dispute but has not elaborated. Paul's senior adviser said the senator had not had a conversation with Boucher in years.
Paul tweeted he will be ready to move forward with tax cuts in the coming days.
