(The Hill) — The Texas Republican Party adopted a new platform declaring that the 2020 election violated the Constitution and President Biden “was not legitimately elected.”

The Texas GOP adopted the 40-page platform at its biennial convention in Houston, which concluded this weekend.

“We reject the certified results of the 2020 presidential election, and we hold that acting President Joseph Robinette Biden Jr. was not legitimately elected by the people of the United States,” the platform reads.

James Wesolek, the Texas GOP’s communications director, told The Hill that the resolution passed by voice vote.

The platform claims that “substantial election fraud” in “key” metropolitan areas affected results in five states, swinging the election in Biden’s favor. 

The party also claimed various secretaries of state, who serve as the top elections official in many states, “illegally circumvented” state legislatures, committing constitutional violations.

“We strongly urge all Republicans to work to ensure election integrity and to show up to vote in November of 2022, bring your friends and family, volunteer for your local Republicans and overwhelm any possible fraud,” the platform states.

There is no evidence of widespread voter fraud in the 2020 election, and a coalition of leading federal and state election officials said the contest was the “most secure” election in American history. 

Several recounts and audits have also confirmed that former President Trump lost several key states. But Trump has continued to repeatedly give voice to baseless claims of voter fraud.

The platform’s passage comes amid a series of public hearings held by the House select committee investigating the Jan. 6, 2021 attack on the Capitol. 

The panel has sought to connect Trump’s claims of voter fraud to the riot that disrupted the counting of the Electoral College votes. The committee showed testimony at its second hearing revealing that many members of Trump’s inner circle did not believe he had won the election.

Republicans in state governments across the country have pushed legislation to restrict access to the ballot in the wake of the 2020 race as candidates aligned with Trump are still claiming that widespread fraud marred the election.

A Republican-led county commission in rural New Mexico refused to certify the state’s primary election results last week without raising specific concerns about discrepancies, leading the New Mexico Supreme Court to step in after a request from New Mexico’s Democratic secretary of state. 

More than a third of Americans — 38 percent — said that they believe that Biden did not legitimately win the 2020 election, according to a poll from The Economist/YouGov earlier this month.

The new Texas state party’s platform also includes sections declaring homosexuality as “abnormal” and opposition to “all efforts to validate transgender identity.”
