"The Kelly File" has extensively highlighted this week Sen. Harry Reid's (D-Nev.) apparent admission that he lied in 2012 when he declared on the Senate floor that Mitt Romney had not paid his taxes for years. 

Fact-checkers called out Reid repeatedly, but he always stuck to his statement. Then on CNN this week, Reid told Dana Bash he had no regrets about what he said.

“So no regrets about Mitt Romney, about the Koch brothers, because people have even called it McCarthyite," Bash asked.

"Well, they can call it whatever they want,” Reid said. “Romney didn’t win, did he?”

Jon Ralston, host of "Ralston Live" on PBS and a Politico contributing editor, told Megyn Kelly Thursday night that he attempted to report on the Reid-Romney issue in 2012 in a column for the Las Vegas Sun. 

But he says the paper's editor, Brian Greenspun, refused to publish it out of a concern that it was too critical of Reid.

"Brian Greenspun runs the newspaper. He went to school with Bill Clinton, very close to Harry Reid. Obviously wanted Harry Reid to be protected and spiked the column," said Ralston. 

Ralson, a leading political commentator in Nevada for years, left the paper shortly thereafter to start his own website, Ralston Reports.

He published the spiked column on his site this week. 

Ralston said he had a "contentious" conversation with Greenspun after he learned about the decision and was given "lame excuses" for why it wouldn't be published. 

"He said I shouldn't use the word McCarthy to describe Reid and that the tone was too harsh. In that same conversation, he admitted to me that he had used the word McCarthyite in a column about Michele Bachmann. So I guess that was OK for him to say that about her, but not for me to say it about Reid. By the way, it was a very apt description looking back," said Ralston. 

After that phone call, Ralston said he decided he would never write another column for the paper.
