Senate Majority Leader Mitch McConnell said Monday that Sen. Rand Paul’s injuries after being personally attacked over the weekend create another potential “challenge” for the Republican Senate that holds a slim two-vote majority as it looks to enact the GOP agenda.

McConnell told reporters in Kentucky Monday that he hopes Paul is able to recover soon after he was attacked by a neighbor over the weekend and suffered five broken ribs. It is unknown when Paul, also of Kentucky, will return to Washington.
