Bill Kristol appeared with Steve Malzberg on Newsmax TV Tuesday to discuss Donald Trump’s influence on the Republican presidential field. The boss argued that despite Trump’s inappropriate comments about illegal immigrants, Republicans should not be so quick to disregard the issues the real-estate mogul has raised, including illegal immigration and the threat of China.

“I’m not a Trump fan, I don’t think he should be the Republican nominee, but, you know, it’s ridiculous. It’s very, very foolish if the Republican establishment and Republican candidates treat him with disdain instead of saying, you know what, good to have more voices, good to have some unconventional voices in the race,” said Kristol.
