Gun-rights activist Marjorie Taylor Greene defeated physician John Cowan in a runoff election for the Republican nomination in Georgia's deep-red 14th Congressional District on Tuesday, AP reports.

Why it matters: Greene, a vocal QAnon conspiracy theorist who has been condemned by GOP leaders for making multiple offensive remarks about Black people, Jews and Muslims in Facebook videos, is likely to win a seat in the House come November.

• QAnon is a far-right conspiracy theory that purports without proof that posts by an anonymous internet user from within the federal government are alluding to a secret war that the "deep state" is waging against President Trump.
• The FBI identified fringe conspiracy theories, like QAnon, as domestic terrorist threats in 2019, according to Yahoo News.

Context: Greene defended QAnon in a 30-minute video and claimed that Black people "are held slaves to the Democratic Party," in a Facebook video published by Politico.

• She also said Muslims should not serve in government, called George Soros a Nazi and claimed that the 2017 Las Vegas shooting was a targeted operation to help pass "anti-gun legislation." Soros is a Holocaust survivor.

House Republican leaders, including Minority Leader Kevin McCarthy, criticized Greene for the videos after they surfaced.

• The No. 2 House Republican, Rep. Steve Scalise of Louisiana, helped Cowan raise money and contributed to his campaign.

What she's saying: "The GOP establishment, the media, & the radical left, spent months & millions of dollars attacking me," Greene tweeted Tuesday night. "Tonight the people of Georgia stood up & said that we will not be intimidated or believe those lies."

• In her victory speech, Greene criticized House Speaker Nancy Pelosi, saying, "She’s a hypocrite. She’s anti-American. And we’re going to kick that b**** out of Congress, according to the Atlanta Journal-Constitution.

What's next: Greene is one of almost a dozen GOP candidates who have openly supported or defended the QAnon movement or some of its tenets.

• Lauren Boebert, a Republican running for Colorado's 3rd Congressional District, is also likely to win a seat in the House in November.
