Douglas Vincent Mastriano (born January 2, 1964) is an American far-right[1][2][3][4] politician and retired military officer who has served in the Pennsylvania Senate since 2019, representing the 33rd district.

[22] During his 2022 run for governor of Pennsylvania, formal complaints were made to the University of New Brunswick (UNB) about potential academic fraud contained in his book published about Alvin York.

[32] In 2024, Mastriano filed a lawsuit against the University of New Brunswick, alleging them of "leaking his doctoral thesis and of participating in a scheme to discredit his research on a First World War hero".

[42] On January 22, 2019, Mastriano announced that he intended to run for the State Senate seat being vacated by Rich Alloway in the 33rd District, saying he "can't, in good conscience, stand aside", wanting to "serve his country in a new way".

[47][49] After the fire at the Notre-Dame cathedral in Paris, Mastriano had shared an image that was circulated implying that it had been an act perpetrated by Muslim terrorists,[50] with a caption reading "something wicked comes this way".

In December 2022, Mastriano posted photos of contrails over his senate district and linked to an article discussing a government research proposal to investigate whether releasing aerosols into the upper atmosphere to reflect solar radiation would combat climate change.

"[57] In early summer 2020, fictitious rumors circulated online that a July 4 protest near Gettysburg National Military Park would involve burning the US Flag and calling for the removal of Confederate monuments and memorials.

"[60] On March 17, 2020, Mastriano called for suspension of the HIPAA law to allow the Department of Health to share more COVID-19 data, including publishing the names and addresses of those infected with the virus.

[61] On March 28, 2020, during the COVID-19 pandemic, Mastriano proposed legislation that would allow Pennsylvania businesses to reopen if they followed CDC mitigation guidelines, subject to health department and law enforcement inspections.

[64] On May 11, 2020, Mastriano called for the resignation of Secretary of Health Rachel Levine, saying she was "being complicit in the virus spreading through our elder care homes, triggered by unscientific and illogical directives, forcing them to readmit COVID-19 patients", and that she was "responsible for the deaths of approximately 2,500 of our citizens, and display[ing] the gross incompetence of someone unfit for office".

[76] Mastriano was a vocal opponent of the implementation of municipal separate storm sewer systems (MS4) programs as applied by the Pennsylvania Department of Environmental Protection.

[77] In an op-ed, Mastriano wrote, in part,: A week rarely passes without me hearing from multiple residents who have been severely impacted by Harrisburg's latest revenue scheme.

[89] The editorial described him as someone who "regularly spouts his love of freedom" but has a relationship to Trump that had been "exposed as nothing more than a vassal doing his master's bidding", and said his actions were that of a "craven oligarch" making a "shocking call for tyranny" in a "campaign to undercut democracy itself for a generation".

[101] On the morning of January 13, Mastriano wrote on Twitter and Facebook, "Please do not participate in rallies or protests over the next ten days," and "Let's focus on praying for our nation during these troubling times.

[108] Transcripts released by the January 6th Committee later showed that investigators were aware of Mastriano's attempt to contact Vice President Mike Pence on the day of the attack.

[116] Wake TSI, the business contracted to do the audit in Fulton County, Pennsylvania by a nonprofit group was directed by discredited Trump attorney and conspiracy theorist Sidney Powell,[117] though she and they never found evidence of fraud.

[118] On February 15, 2022, Mastriano was subpoenaed by the congressional committee investigating the January 6 attack on the U.S. Capitol, reportedly to inquire about his role in trying to impanel a slate of alternative electors in Pennsylvania, in an effort to overturn the 2020 presidential election.

[120] Mastriano has compared the actions of the committee as similar to the Nazi Party's crackdown on civil liberties following the Reichstag fire, and making "McCarthy in the '50s look like an amateur".

But he answered no questions and ended the session after only fifteen minutes, after several disputes were brought up by his lawyer, including Mastriano's request that he be allowed to record his deposition, something the committee denied.

The complaint was based of a report by Citizens for Responsibility and Ethics in Washington (CREW) which outlined Mastriano's involvement in attempts to overturn the election and January 6.

[11][129] The conference promoted conspiracy theories claiming that there is a global cabal of Democrats sex trafficking children, 9/11 was a false flag attack, vaccines amount to genocide therapy and Adolf Hitler faked his death.

[141] Shapiro has argued that Mastriano's anti-abortion views will cost Pennsylvania business and jobs as some Pennsylvania-based corporations, such as Duolingo, have said they will leave the state if an abortion ban is passed.

[127] A number of candidates including President pro tempore of the Pennsylvania Senate Jake Corman and former Congresswoman Melissa Hart dropped out and endorsed Lou Barletta, in a bid to stop Mastriano.

[176] In August, Mastriano was placed on their list of "right-wing extremists" seeking elected office and once again condemned by the ADL after spreading debunked, antisemitic, conspiracy theories that George Soros, a Jewish liberal businessman, was a Nazi.

[176] In August 2022, Mastriano condemned the FBI search of Mar-a-Lago, the residence of former president Trump, as "an outrageous weaponization of America's tools of justice against political opponents of the current regime in Washington, DC".

[189] Green has prophesied that a number of politicians including Liz Cheney, Doug Ducey, Mitch McConnell, Jerry Nadler, Mitt Romney and Chuck Schumer will be executed for treason.

[189] An August 2022 investigation by LNP found that Mastriano's security detail was made up of non-professional, armed guards including the former regional leader of the Oath Keepers, a far-right extremist militia group.

[199] The page features posts stating that Michelle Obama is transgender, George Soros is a Jewish puppet master who controls politicians and that immigrants are "scary brown people".

[200] In late August 2022, Reuters obtained a photograph via a FOIA request showing Mastriano dressed in a Confederate uniform while posing in a 2013–14 faculty portrait for the Army War College.

"[201] Following the controversy, Media Matters for America published a Facebook livestream from Mastriano in 2020 where he praised armed men, who were ostensibly defending a statue of Confederate General Robert E. Lee in Gettysburg National Park.
