Presidential hopeful makes comment after Senate Republican leader, 81, froze and was unable to speak this week

Presidential hopeful Nikki Haley has suggested her fellow Republican Mitch McConnell – the longtime powerful US Senate leader – should step aside after an episode in which he physically froze and was unable to speak at the Capitol this week.

Appearing on CBS’s Face the Nation on Sunday, Haley was asked by the host Margaret Brennan whether she still had confidence in McConnell’s ability to lead after the episode.
