Nikki Haley is once again pressing Washington’s greying political establishment to step aside after a pair of concerning moments involving two of the Senate’s oldest members grabbed headlines in recent days. The former South Carolina governor and UN ambassador spoke to CBS’s Margaret Brennan in an interview that aired on Sunday; she is currently campaigning in early primary states as she seeks the GOP nomination for president. A central tenet of her campaign’s message since its onset has been a call for a new generation of leaders to take the helm in both parties. As such, Brennan asked her about the moment that Senate Minority Leader Mitch McConnell froze and appeared unable to speak at a press conference on Wednesday, after which he was led away by a colleauge. It was later revealed that the Senate GOP leader had suffered an undisclosed fall earlier in July while still recovering from a concussion suffered in the spring. “I think Mitch McConnell did an amazing job when it comes to our judiciary. When we look at the judges, when we look at the Supreme Court, he's been a great leader. But I do think that this is one – you know, we've got to stop electing people because they look good in the picture or they hold a baby well,” she told CBS News. “We've got to stop electing people because we like them and they've been there a long time. That's actually the problem. You need to have term limits, because we need new ideas, new solutions. We've got to have a new generation.” Ms Haley added when pressed by Brennan on whether she had confidence in Mr McConnell remaining leader of the Senate Republican caucus: “What I am saying about Mitch McConnell, Dianne Feinstein, Joe Biden, Nancy Pelosi, all of them: know when to walk away, know when to walk away. We have huge issues that need new solutions. We need new generational leaders. We appreciate your service. We appreciate what you've done. But this is why we will fight for term limits. We've got to get it done in America.” Her remark naming Senator Feinstein was an apparent reference to another moment that drew the attention of reporers this past week when the senior senator from California appeared confused during a committee hearing and launched into a speech calling for a vote which was already in progress. And persistent concerns about Joe Biden’s age have followed him doggedly throughout his first term. The 80-year-old Mr Biden was already the oldest US president to be sworn into office in 2021, and is now facing some calls from progressives and others concerned about criticisms focused on his mental acuity to step aside and allow a younger politician to be the Democratic Party’s standard-bearer. Ms Pelosi’s inclusion on the list is only notable given that she is the sole named party leader to have already given up her leadership position, willingly, earlier this year. The 83-year-old California congresswoman handed over command of the Democratic caucus to Hakeem Jeffries at the beginning of the year while Republicans struggled to annoint their own leader in a chaotic speakership election. Ms Haley was less certain in her interview with CBS whether Donald Trump, 77, would be included in her call for ageing politicians to step aside. But she maintained that he should take a mental acuity test, as she argues all presidential contenders should. And she relented after pressing from Brennan that Mr Trump was “of course” not who she had in mind when she made her call for leaders with new ideas, age notwithstanding. “I just said we need a new generational leader,” she noted. “I mean, that goes ... for all of them. You can look across DC ... Of course, I'm talking about Trump. I've said that all throughout this campaign that it is time for us to have a new generation. We've lost – Republicans have lost the last seven out of eight popular votes for president. That's nothing to be proud of, we should want to win the majority of Americans, we've got to start going with a new generation so that we can do that. “ Read More Mitch McConnell vows to serve out full Senate term following questions over his health Sen Dianne Feinstein appears confused and is instructed to vote ‘aye’ by fellow senator at meeting Mitch McConnell leaves press conference abruptly after appearing unable to speak Joe Biden, America's oldest sitting president, needs young voters to win again.
