"[30] McKinney and other members of the House of Representatives objected to the 25 electoral votes from Florida which George W. Bush narrowly won after a contentious recount.

In a statement in April 2002, McKinney told The Washington Post: "I am not aware of any evidence showing that President Bush or members of his administration have personally profited from the attacks of 9–11.

[39] McKinney protested the result in court, claiming that thousands of Republicans had voted in the Democratic primary, the real contest in the district, in revenge for her anti-Bush administration views and her allegations of voter fraud in Florida in the 2000 presidential election.

It interpreted the Supreme Court's Jones ruling to hold that the right to association involved in a dispute over a primary—and thus, standing to sue—belongs to a political party, not an individual voter.

[42][43] Other factors in McKinney's defeat included her allegations of Bush's involvement in 9/11,[34][44] her opposition to aid to Israel, a perceived support of Palestinian and Arab causes, and open antisemitism in her comments.

[49] Georgia political analyst Bill Shipp addressed McKinney's defeat saying: "voters sent a message: 'We're tired of these over-the-top congressmen dealing in great international and national interests.

[51] Having made no secret that she wanted to return to Congress, McKinney turned down the Green Party's nomination for president in the 2004 presidential election.

[52] Majette declined to run for re-election to the House, opting instead to become a candidate to replace retiring Senator Zell Miller, a conservative[citation needed] Democrat.

An Atlanta Journal-Constitution editorial[60] said that the purpose of the event was to discuss whether or not the Bush administration was involved in the 9/11 attacks, expressing surprise that McKinney was once again taking on the issue that was believed to have cost her House seat.

[61] The 9/11 Commission has sealed all the notes and transcripts of some 2,000 interviews, all the forensic evidence, and both classified and non-classified documents used in compiling its final report until January 2, 2009.

In questioning Department of Homeland Security Secretary Michael Chertoff, McKinney referred to a news story in which the owners of a nursing home had been charged with negligent homicide for abandoning 34 clients who died in the flood waters.

"[72] The Congressional Black Caucus' Omnibus Bill (HR 4197) was introduced on November 2, 2005, to provide a comprehensive response to the Gulf Coast residents affected by Hurricane Katrina.

[73] At the request of McKinney, the Select Bipartisan Committee to Investigate the Preparation for and Response to Hurricane Katrina,[74] chaired by Thomas M. Davis, held a previously unscheduled hearing titled "Voices Inside the Storm" on December 6, 2005.

[78] On the morning of March 29, 2006, McKinney entered the Longworth House Office Building's southeast entrance and proceeded past the security checkpoint, walking around the metal detector.

In the midst of a media frenzy, McKinney made an apology[79] on the floor of the House of Representatives on April 6, 2006, neither admitting to nor denying the charge, stating only that: "There should not have been any physical contact in this incident."

At her April 23, 2006, "District Days" event, McKinney was being interviewed by WGCL's Renee Starzyk, who repeatedly questioned her about the March 29 scuffle with a Capitol police officer.

[citation needed] Documents relating to the death of rapper Tupac Shakur, in which McKinney took an active interest, would be released under another bill she would introduce.

CNN reported that during her concession speech, McKinney hardly mentioned her opponent but praised the leftist political leaders elected in South America.

"[88] At an August 27, 2007, peace rally in Kennebunkport, Maine, McKinney confirmed the depth of her disenchantment with the Democratic Party, urging San Francisco voters to replace Nancy Pelosi with antiwar activist Cindy Sheehan.

[92] On September 10, 2008, McKinney joined a press conference held by third-party and independent candidates, along with Ralph Nader, Chuck Baldwin, and initiator Ron Paul.

[95][96] In one post she related the conspiracy theory that individuals such as George Soros and Alan Greenspan (both Jewish) have plotted to create a "one-world government".

[97][98] Israeli officials claimed that the collision was accidental and occurred after the ship was informed they would not be allowed to enter Gaza and tried to outmaneuver the patrol boat; they decried McKinney's actions as being irresponsible and provocative for the sake of propaganda.

[98][99] On June 30, 2009, McKinney was aboard the Greek-flagged Free Gaza Movement's ship Spirit of Humanity carrying 21 activists including Irish peace activist Mairead McGuire, medical supplies, a symbolic bag of cement, olive trees and toys, when it was seized by the Israeli Navy 18 mi (29 km) off the Gaza coast.

[103][104][105][106][107] According to The Atlanta Journal-Constitution, Israeli officials stated that the "Palestinian Authority and the rest of the international community had agreed to the off-shore blockade to prevent arms smuggling into Gaza.

[116] In May 2020, The Algemeiner Journal and other media outlets reported that McKinney released a series of statements via Twitter questioning the true number of Jewish people murdered during The Holocaust.

"[11] The Washington Post noted that, amid a sitewide increase in hate speech following Elon Musk's purchase of Twitter, McKinney had prominently amplified and made tweets in 2022 containing an antisemitic hashtag mainly used by neo-Nazis to imply a conspiracy of Jewish people in positions of power.

[129] On June 14, 2000, a part of Memorial Drive, a major thoroughfare running through her district, was renamed "Cynthia McKinney Parkway," but the naming has come under scrutiny since her primary defeat in 2006 as well as previous controversial statements that she had made.
