CHUCK TODD: Okay, last quick question. Is there one thing that John Kelly should avoid doing as President Trump's chief of staff?
COREY LEWANDOWSKI: Absolutely. The thing that General Kelly should do is not try to change Donald Trump. Chuck, as you know, I say you have to let Trump be Trump. That is what has made him successful over the last 30 years. That is what the American people voted for. And anybody who thinks they're going to change Donald Trump doesn't know Donald Trump.
CHUCK TODD: I think that's a good place to end. Corey Lewandowski, thanks for coming on the show. Appreciate you coming on and sharing your views, sir.
COREY LEWANDOWSKI: Thank you.
CHUCK TODD: All right, when we come back, as the presidential candidate, Donald Trump won by breaching the Democrat's Midwestern blue wall. Six months into his presidency, how's that wall holding up now?
