Just weeks after Fox News host Megyn Kelly's vaunted interview with GOP frontrunner Donald Trump – referred to by some as the posterior kiss heard around the world – the pair seem to have returned to their adversarial ways.

On her show The Kelly File on Thursday the anchorwoman again blasted Trump for calling U.S. District Judge Gonzalo Curiel's Mexican heritage of “a conflict of interest.”

Judge Curiel is currently overseeing a fraud lawsuit against Trump University, widely derided by former participants as a money making scam, and Trump is reportedly attempting to undermine his credibility.

“You tell me - I’m a journalist here at Fox News and I’ve been doing legal commentary here for 10 years - this is out of line,” Kelly told guest Bill Bennett on her show The Kelly File.

Bennett, an Irish American conservative pundit, replied: “Yeah it’s out of line. It’s a shame too, because it was a good day, it was an important day for Trump.” GOP Speaker Paul Ryan's long awaited endorsement is being overshadowed by Trump's racially incendiary remarks, Bennett added.

“I'm Irish, that doesn't mean I support the IRA,” Bennett scoffed.

Kelly, a former attorney, is especially sensitive to the implications of Trump's comments and he noted that the judicial code of conduct prevents Curiel from personally responding to Trump’s accusations.

“People are saying this judge is a member of La Raza, the group that's been protesting Donald Trump. He isn't! He's a member of a Hispanic lawyers association that has no partisan stripes whatsoever.”

“Secondly, the man is not Mexican. His parents are Mexican, he's of Mexican heritage. He was born in Indiana.”

“Third, he has no conflict of interest. Now Donald Trump is saying the judge needs to be investigated, someone should look into him just because he's ruled against Donald Trump in this litigation repeatedly.”

Following the law or offering criticism doesn't immediately mean you biased Kelly argued. “It doesn't!”

The truce with Trump appears to be over.
