Senator Rand Paul said he's recovering well from the November assault that left him with six broken ribs, and he added violence against political figures has been a concern among his colleagues.
The Kentucky Republican told CBS' "Face the Nation" that fellow lawmakers don't want to think it's open season on elected officials.
But he said his own injuries and the June shooting that wounded members of Congress at a baseball practice in Virginia have made an impression on lawmakers.
Paul was pressed during the television interview about whether political grievances led his neighbor to tackle the senator while he was mowing his lawn. Paul gave no opinion and said people have been too focused on attackers' motivations rather than on punishment and deterrence.
