WASHINGTON — GOP Rep. Marjorie Taylor Greene delivered an apologetic speech on the House floor on Thursday, describing herself as a “very regular American” who fell into the QAnon conspiracy theory.

The firebrand Georgia lawmaker repented ahead of a vote on whether to strip her of her committee assignments after Greene’s incendiary activity online came to light last month — sparking a furor in Congress.

“I was allowed to believe things that weren’t true and I would ask questions about them and talk about them, and that is absolutely what I regret,” Greene said.

“I never once said during my entire campaign, QAnon. I never once said any of the things that I am being accused of today during my campaign. I never said any of these things since I have been elected for Congress,” she said.

“They do not represent my values.”

Senate Minority Leader Mitch McConnell (R-Ky.) ripped Greene as a “cancer” on the party, but House Minority Leader Kevin McCarthy (R-Calif.) decided to keep the Georgia Republican in her Education and Budget committee assignments.

Greene in the past has claimed that mass shootings are “false flag” operations by gun control advocates, questioned whether the 9/11 terror attacks at the Pentagon were a result of a hijacked plane, and “liked” a Facebook post that said House Speaker Nancy Pelosi (D-Calif.) should be executed.

“School shootings are absolutely real and every child that is lost, those families mourn it,” Greene said Thursday.

“I understand how terrible it is because when I was 16 years old, in 11th grade, my school was a gun-free school zone, and one of my schoolmates brought guns to school and took our entire school hostage. And that happened right down the hall for my classroom,” she went on.

A video also emerged last month of Greene berating Marjory Stoneman Douglas High School shooting survivor David Hogg in Washington, DC, and she bragged about it in an April 2019 interview in which she called Hogg an “idiot” who “only talks when he is scripted.”

“I also want to tell you 9/11 absolutely happened. I remember that day, crying all day long, watching it on the news, and it’s a tragedy for anyone to say it didn’t happen,” Greene added Thursday.

But the lawmaker also railed against big tech and the media, accusing liberal networks CNN and MSNBC of distorting her views and pushing claims that former President Donald Trump colluded with Russia to win the 2016 election, something she said was also a “conspiracy theory.”

And she echoed GOP concerns when she sounded-off against Democratic lawmakers like Rep. Ilhan Omar who remains on the House Foreign Affairs Committee despite her history of anti-Semitic remarks and Democrats who had condoned riots and unrest during last year’s Black Lives Matter demonstrations.

The 46-year-old lawmaker who was elected to represent the Peach State’s northern 14th congressional district in November, described herself as unapologetically pro-life.

“I believe in God with all my heart and I’m so grateful to be humbled to be reminded that I’m a sinner. And that Jesus died on the cross to forgive me for my sins,” she said.

“I will work with you for good things for the people of this country but the thing is, I will not stand for abortion. I think it’s the worst thing this country has ever committed. And if we’re to say ‘In God We Trust’, how do we murder God’s creation in the womb?” she asked.

Republicans have rebuked Greene’s comments as “absolutely repugnant” and indefensible, but have pushed back on the Democrat-led House vote to remove the Georgia lawmaker from the two committees she serves on.
