NEW YORK (AP) — NBC’s Lester Holt says watching an exasperated reporter recently confront Sarah Huckabee Sanders about the Trump administration’s hostility toward the press nearly made him physically ill.

It’s just not his style. Holt exudes an aura of calm as anchor of NBC’s “Nightly News,” which is in a tight battle with ABC and David Muir every night for viewers and advertising dollars.

He appears so steady that it’s surprising to hear him talk about how tough it was to replace Brian Williams when scandal forced his predecessor out two years ago. Holt said there were times when he wondered whether if it was what he really wanted to do.
