A dentist, lawyer,[9] and former real estate agent,[10][11] Taitz was a figure in the "birther" movement, which promoted the conspiracy theory that Barack Obama was not a natural-born citizen eligible to serve as president of the United States.
[12][14] Taitz lives in Laguna Niguel, California,[15] and owns dental practices in nearby Mission Viejo and Rancho Santa Margarita.
[16][17] Before her national news exposure, Taitz was quoted in The Orange County Register in 2006 supporting Israeli military actions against Hamas and Hezbollah,[18] and downplaying the impact of the espionage trial of two American Israel Public Affairs Committee staffers.
[21] Taitz has stated that 2016 Republican presidential candidates Ted Cruz, Marco Rubio, and Bobby Jindal were not natural-born citizens and therefore were ineligible for the office they sought.
[26][27] In November 2008, Taitz, acting on behalf of independent presidential candidate Alan Keyes, sued California's secretary of state, Debra Bowen, for allegedly failing to ascertain Obama's eligibility for the presidency before placing him on the ballot.
[1] Taitz filed a lawsuit on behalf of Pamela Barnett, Alan Keyes, other candidates in the 2008 federal elections, several military personnel, and some legislators from various states alleging that Obama was ineligible to be president.
[35] Taitz represented Stefan F. Cook, a major in the United States Army Reserve, who challenged orders implementing his voluntary deployment to Afghanistan because of his claim that Obama was not a legitimate president.
He also expressed astonishment at Taitz's apparent misunderstanding of American judicial fundamentals, saying that she was trying to make Obama "'prove his innocence' to 'charges' that are based upon conjecture and speculation".
[50] In the meantime, on August 9, the federal government filed an abstract of judgment, a document placing a lien in the amount of $20,000 plus interest on all her real property,[51] prompting Taitz to say, "I will pay the money, and I will continue fighting," should it happen that her application for stay is ultimately denied and that the Supreme Court consents to her request to authenticate Justice Thomas's signature.
"[58][59] In August 2011, Taitz filed, in propria persona, a suit against the director of the Hawaii Department of Health, seeking to review Obama's "long form" birth certificate.
[61] Taitz sought to compel White House Counsel Kathryn Ruemmler under FOIA to grant access to Obama's "long form" birth certificate.
"[68] Five Georgians, including one represented by Taitz, filed challenges with the Georgia Secretary of State, Brian Kemp, regarding Obama's inclusion on the March primary ballot.
This normally would result in a default order, but the challengers requested Malihi to allow them to go ahead with the hearing and rule on "the merits of their arguments and evidence".
Concerning Taitz's case Malihi wrote: "The Court finds the testimony of the witnesses, as well as the exhibits tendered, to be of little, if any, probative value, and thus wholly insufficient to support plaintiffs’ allegations".
Taitz made false claims, arguing that the President's surname was not Obama, that he was not a natural-born citizen, and that he was using a stolen Social Security number.
In response, the party filed with the court a certified verification from Hawaii's State Registrar attesting to the accuracy of Obama's birth certificate.
[89] Taitz filed a lawsuit in Indiana, and attempted to subpoena Maricopa County, Arizona Sheriff Joe Arpaio and one of his assistants, Mike Zullo, to compel them to testify about the results of their investigation into Obama's birth certificate.
[90] In September 2012, Taitz attempted to address a Kansas state board that had been reviewing a challenge to Obama's placement on the ballot, but her request to speak was denied.
[95] In a lawsuit initiated by Taitz, she falsely claimed Obama's birth certificate and Social Security Number were fake, and sought to disqualify him from the ballot.
On January 3, 2013, District Judge Morrison C. England Jr. denied the plaintiffs' request for a temporary restraining order to prevent Congress from certifying the Electoral College's vote.
At the hearing, the judge told Taitz, "Your argument, it doesn't make any sense whatsoever," and at one point asked, "Why do you keep filing these lawsuits when they keep getting rejected?
[99] Believing that the death of Loretta Fuddy (the director of the Hawaii Department of Health) was not an accident, Taitz sued the Hawaiian Memorial Park Mortuary in Federal district court on December 20, 2013, to prevent a cremation.
[103] In 2014, Taitz filed a lawsuit challenging the transfer of undocumented immigrants from South Texas to other states, claiming they would spread communicable diseases.
[111] In 2015, Taitz filed a third lawsuit in Texas, alleging the federal government's grant of asylum and refuge status encouraged undocumented immigrants to engage in identity theft.
[114] In 2021, Taitz unsuccessfully sued Vice President Kamala Harris and Senate Majority Leader Chuck Schumer to stop the second impeachment trial of Donald Trump.
[121] On June 17, 2010, Taitz filed a lawsuit in the Orange County Superior Court contesting the election results, again alleging Dunn's ineligibility.
[1] Various media outlets described her appearance on the network as an "implosion",[1][143] as Taitz asserted that Shuster, who is Jewish, was a "brownshirt", a charge she repeated in a phone interview the following week.
In response, she and pastor James David Manning organized a protest outside Fox News headquarters in New York City in November 2009, which drew an estimated 15 to 20 attendees.
[144] In April 2011, Lawrence O'Donnell invited Taitz on MSNBC so that she could address President Obama's long form birth certificate, which had been released the day before.
When Taitz only wanted to make false claims about President Obama's alleged Selective Service papers and refused to comment on his birth certificate, O'Donnell kicked her off the show, stating: "Look, she's crazy.
