Fox News anchors were shocked when a guest openly called Sen. Kamala Harris a religious bigot on the air.

GOP strategist and GOPAC chairman David Avella discussed Harris as one of the many Democrats who may be looking at challenging President Donald Trump in the 2020 election when he made his remarks on “America’s Newsroom” on Friday.

Avella noted the “craziness” over the more than two dozen potential Democratic candidates during the panel discussion, noting how some “aren’t even going to make it out of the gate.”

He then turned the focus on Harris, the California senator who has not yet announced a bid for the White House, but is widely reported to confirm the speculation in the coming weeks.

“Even for the Democrats, it’s hard to see them nominate a very clear religious bigot in Kamala Harris,” Avella said, prompting a moment of surprised silence form the panel.

“Whoa! Why do you say that?” Wall Street Journal’s Shelby Holliday asked.

Avella referenced Harris’ written questions to Brian Buescher, Trump’s nominee to the District Court in Nebraska, about his membership in the Catholic fraternal charity organization, the Knights of Columbus. Last month, Harris, along with fellow Senate Judiciary Committee member Sen. Mazie Hirono of Hawaii questioned the appropriateness of Buescher’s participation in the “all male society” that “has taken a number of extreme positions” on social issues.

The Democrats drew scathing rebukes for their anti-Catholic “bigotry” and prompted the Washington, D.C.-area Knights of Columbus Council to issue an open letter in December inviting the lawmakers to come see their events in person.

“If being a part of the Knights of Columbus disqualifies you from serving in an administration, we’ll have reached a new era in America,” Avella contended on Friday.

Rep. Tulsi Gabbard called out fellow Hawaii Democrat Hirono in an op-ed in The Hill published Tuesday, criticizing those “fomenting religious bigotry” in questioning whether Buescher would remain impartial on abortion and same-sex marriage issues.

“While I oppose the nomination of Brian Buescher to the U.S. District Court in Nebraska, I stand strongly against those who are fomenting religious bigotry, citing as disqualifiers Buescher’s Catholicism and his affiliation with the Knights of Columbus,” Gabbard, herself a potential 2020 presidential candidate, wrote.

“While I absolutely believe in the separation of church and state as a necessity to the health of our nation, no American should be asked to renounce his or her faith or membership in a faith-based, service organization in order to hold public office,” Gabbard wrote.
