How to tell whether a candidate is a bigot: What’s a good sign?

The Republican National Committee announced Monday that its official candidate for U.S. Senate, Virginia Republican Sen. Tim Kaine, is a “white supremacist” and “anti-gay bigot.”

The statement, released Monday night, came after The Daily Beast and the Associated Press reported that Kaine was the subject of a racist, homophobic email from his son, who was the communications director for President Donald Trump’s campaign.

In his statement to The Hill, Kaine acknowledged the emails “were sent by a former colleague,” but insisted that his son was “a good friend of mine” and that he is not racist or anti-gay.

Kaine’s campaign has yet to respond to The Daily Caller’s request for comment.

However, the GOP nominee’s son has also come under fire from the party, with some accusing him of bigotry and inciting hatred against people of color.

Trump has repeatedly condemned the birther movement that was waged by then-President Barack Obama and his former Democratic predecessor, Bill Clinton, in which many Republicans believed the president was not born in the United States.

The movement gained steam after Trump announced his candidacy in the spring of 2016.

Trump himself also faced backlash after he was accused of calling Sen. Cory Booker (D-NJ) “an embarrassment” and calling Sen “Tyson” in a tweet in May.

Trump’s son and former communications director also had an open feud with then-candidate Sen. Marco Rubio (R-FL) in a January 2016 interview with The Washington Post.

In the interview, the father suggested Rubio would be “a disaster” in office.

During the 2016 campaign, Kaine also received criticism from the Trump campaign for suggesting in a March 2016 email that he could not understand why Sen. Bernie Sanders (I-VT) was “going through such a tremendous personal crisis” after a series of sexual assault allegations against him surfaced.

The DNC said that Kaine’s son was working in the campaign’s communications office and that “the email was not intended to imply endorsement of Mr. Kaine for President.”

The organization did not say if the campaign had contacted the Trump team about the email.

Kurtz previously said that his father has no intention of being the Democratic nominee.

“I think it’s really clear that Tim Kaine is not running for office because he’s not a Democrat, he’s a Republican,” Kurtz told Fox News in March.

“And he’s trying to win his race in the general election and to do that he needs to run in the Senate.

And so that’s why he’s working in politics, I think, for a long time.”
