Senate Minority Leader Mitch McConnell's Health Is Under Scrutiny

Republican lawmakers tell NBC News they have concerns about Senate Minority Leader Mitch McConnell and his health. Their comments come following Wednesday's incident when the Kentucky Republican froze for 19 seconds during a press conference before being escorted away from the cameras. None of the Republicans are calling on McConnell to step down yet; senators next in line for the top job say they are not making succession plans at this time. The murmurings underscore how the party is struggling to deal with the sensitive health issues of the longest serving Senate Party leader in American history.
