Mastriano was among Trump’s most dedicated supporters during the 2020 campaign, and the night Trump’s loss became evident on Nov. 7, he addressed a few thousand disappointed Trump supporters outside the Pennsylvania Capitol.
As Trump’s efforts to overturn the results gathered speed in the ensuing weeks, Mastriano helped organize and host a four-hour state Senate Republican policy hearing regarding the election, held Nov. 25 at a hotel conference room in Gettysburg. Trump lawyer Rudy Giuliani attended, and Trump claimed during a roughly 11-minute video call that the election was rigged.
“This election has to be turned around,” Trump told the Gettysburg crowd.
Mastriano traveled to the White House the evening of the Gettysburg hearing for a private event to strategize about the election results, but tested positive for COVID-19 and had to leave. He later posted a video on Facebook describing his case as “pretty mild.”
He then urged fellow Republican state senators to join him for lunch with Trump on Dec. 23. In an email to his GOP colleagues sent a day earlier, Mastriano advised them to fill out security details in the RSVP “if you would like to join us for lunch with POTUS at the White House tomorrow.”
During online chats with his growing cadre of supporters and admirers, Mastriano has repeatedly said he’s had regular, direct contact with Trump, boasting about having spoken with the then-president at least 15 times.
Mastriano organized bus trips to the U.S. Capitol on Jan. 6 and advertised himself ahead of time as a scheduled speaker on the Capitol steps during the afternoon. He has described getting prime seats to Trump’s speech before the riot. He subsequently claimed he left the U.S. Capitol area after the eruption of violence, which in the aftermath he called “unacceptable.”
Mastriano was unknown in state political circles when he won a May 2019 special election for a state Senate seat in a mostly rural district that straddles Interstate 81 along the Maryland-Pennsylvania state line. He easily won reelection in 2020.
By spring of 2020, Mastriano had emerged as a leader of opposition to pandemic mitigation efforts, telling protesters they should “rise up” and “say ‘no’ to tyranny.”
Mastriano is not the first Pennsylvanian to be subpoenaed by the committee.
Last month, the House Jan. 6 committee released subpoenas for Bill Bachenberg and Lisa Patton, the two chairpersons of a competing Electoral College meeting held by Republicans in December 2020 to submit rival Pennsylvania electoral votes for Trump.
The committee in December also requested an interview with Republican U.S. Rep. Scott Perry, who has advanced baseless conspiracies about the election being stolen, including on the floor of the U.S. House when he voted to object to Pennsylvania’s electoral votes being cast for Biden.
The letter to Perry said he had “an important role” in efforts to install Justice Department official Jeffrey Clark as acting attorney general. Perry declined the committee’s interview, calling the body “illegitimate.”
