Former Republican strategist Steve Schmidt on Sunday laced into former Alaska governor Sarah Palin, blasting her as a "degenerate liar" who should not be afforded the opportunity to once again hold "a position of public trust."

Palin, who served as the 2008 GOP vice presidential nominee under the late Sen. John McCain, is currently running for Congress.

In a Twitter thread, Schmidt, who was a senior campaign strategist and advisor to McCain during the senator's unsuccessful 2008 presidential bid and pushed Palin as a running mate for the GOP nominee, launched a litany of attacks on the ex-governor.

"When the campaign ended I refused to let Sarah Palin speak," Schmidt wrote of the concession speech that he put into motion for McCain to offer on election night in Arizona. "I placed the phone call to Barack Obama for the concession and did everything I could to make sure a beautiful speech wasn't disgraced by the nut ball from Alaska."
