Fox Business host Lou Dobbs criticized Utah Sen. Mitt Romney and other Republican critics of President Donald Trump’s latest comments about late Republican Arizona Sen. John McCain.

Speaking with former Reagan’s campaign director Ed Rollins on Wednesday evening about the president’s recent positive polling within the Republican Party, Dobbs gave GOP chairwoman Ronna McDaniel “great credit” before ripping Trump’s GOP critics.

“These are better numbers than Reagan had and Nixon had when they both had 49 state victories,” Rollins said, referring to the fact that 78 percent of Republicans are enthusiastic about Trump. “I am not predicting that, but I’m simply predicting there are a lot of Republicans out there ready for the fight. They are proud of this president. They want this president reelected.”

“We’re starting to see some movement within the party,” Dobbs noted. “And by the way, I think Ronna McDaniel deserves great credit, the chair of RNC, for holding the line and supporting this president with full support, when there are people like, say, Mitt Romney for example, undercutting this president because he made some nasty remarks about John McCain. There is a reason for those nasty remarks. There is a history between those two men. And the people who are attacking him, including Mitch McConnell attacking the president for his views on John McCain, is asinine.” (RELATED: Trump Says John McCain Put Him In ‘Jeopardy’ By Giving Dossier To FBI)

Dobbs and Rollins ended the segment with a discussion about McCain’s Obamacare vote and the “bad history” between Trump and the late senator.

“I knew John well, and liked him over the years,” said Rollins. “But the reality is Trump did what he had to do and won a big, big election …”
