Freshman lawmaker Marjorie Taylor Greene shared a video in 2018 repeating an anti-Semitic conspiracy espoused by the gunman in the Pittsburgh synagogue massacre.

Rookie member of Congress Marjorie Taylor Greene on Wednesday pushed back at critics and said she is not apologizing for promoting wild conspiracy theories, including one positing that California forest fires could have been caused by lasers from space paid for by Jewish bankers.

The wackiness of her theory was so bizarre that “Jewish Space Laser” was trending on Twitter last week.

It turns out that Greene has a long history of social media posts that read like an encyclopedia of modern fake conspiracy theories.

Greene has pushed the horrific, debunked conspiracy that the grisly Sandy Hook and Parkland school shootings, which killed 47 people, including 34 children, never happened. She also trafficked in the conspiracy that the 9/11 attacks by Islamic terrorists were  “an inside job.”

Greene still claims that Donald Trump won re-election.

Greene is also a proponent of the QAnon conspiracy, which claims a secret cabal of Satan-worshipping, cannibalistic pedophiles is running a global child sex-trafficking ring and plotting against former U.S. President Donald Trump, whom Q-believers say is fighting to defeat the cabal.

Condemned by the Press and her Own Party

Her comments have gotten wide coverage in the press and also attracted intense criticism from Republican party leaders.

Greene shared a video in 2018 “repeating the anti-Semitic claim that ‘Zionist supremacists’ are conspiring to flood Europe with migrants in order to replace the white populations there,” The Jerusalem Post reported in August.

“The 2018 video … repeats an anti-Semitic conspiracy theory called the ‘Great Replacement,’ which alleges that Jews are orchestrating the mass migration of nonwhite immigrants into predominantly white countries in order to wipe out the populations there. It says those supporting the refugees are using ‘immigrant pawns’ to commit ‘the biggest genocide in human history,’” continued The Post.

In 2018, a gunman murdered 11 people in a Pittsburgh synagogue, “espous[ing] the Great Replacement theory, as did marchers in the 2017 far-right rally in Charlottesville,” added The Post.

“I think we should have nothing to do with Marjorie Taylor Greene, and think we should repudiate the things she said and move away from her,” Senator Mitt Romney told reporters, adding Republicans must “separate [themselves] from the people that are the wacky weeds.”

“If we don’t, then our opposition tries to brand us with their image and with their point of view, which has been detrimental to any party that doesn’t do that,” Romney said.

Senior Republican leader Senator Mitch McConnell went so far as to issue a statement, without mentioning Greene by name, calling her “loony lies” a “cancer” on the GOP, The Hill reported.

“Somebody who’s suggested that perhaps no airplane hit the Pentagon on 9/11, that horrifying school shootings were pre-staged, and that the Clintons crashed JFK Jr.’s airplane is not living in reality,” McConnell said. “This has nothing to do with the challenges facing American families or the robust debates on substance that can strengthen our party.”

For her part, Greene refused to back down and tweeted Wednesday that “the radical Democrat mob is trying to silence me, but luckily the People have my back.”

After several Democrats moved to have her expelled from the congressional education committee, Greene tweeted that she had raised over $160,000 in donations to defend herself, ignoring the Republican criticism of her support for debunked conspiracy theories.

“They are only set out to destroy Republicans, your jobs, our economy, your children’s education and lives, steal our freedoms, and erase God’s creation,” Moore tweeted. “And the bloodthirsty media are their henchmen who help them by relentlessly attacking anyone in their path.”

Last Friday, the Republican Jewish Coalition issued a statement condemning Greene, saying the RJC “has always spoken out strongly against anti-Semitic comments from individuals on both sides of the political aisle, and we do not hesitate to do so again in the case of Rep. Marjorie Taylor Greene.”

“The RJC has never supported or endorsed Marjorie Taylor Greene. We are offended and appalled by her comments and her actions. We opposed her as a candidate and we continue to oppose her now,” the statement said. “She is far outside the mainstream of the Republican Party, and the RJC is working closely with the House Republican leadership regarding next steps in this matter.
