Just as he was targeted by the Jan. 6th committee, former Trump lawyer John Eastman took a trip to Wisconsin to push Republican officials to decertify the 2020 election. Via ABC News:

Eastman, a right-wing lawyer who drafted a plan for former President Donald Trump to cling to power by falsely claiming then-Vice President Mike Pence could reject legitimate electors during the 2020 presidential election, was part of a small group of Trump allies who secured a private meeting last month to try and convince the Republican leader of the Wisconsin state Assembly to decertify President Joe Biden’s win, multiple sources familiar with the meeting told ABC.

On March 16, Eastman and others spent nearly two hours behind closed doors pressuring Republican Wisconsin Assembly Speaker Robin Vos to nullify the 2020 election and reclaim the electors awarded to Biden, the sources said, which legal experts say is impossible.

[...] Eastman in the meeting urged Vos to decertify the election, sources familiar with the meeting said. According to Jefferson Davis, a Wisconsin activist pushing to reverse Biden’s victory who was also in the meeting, Trump’s former lawyer pushed Vos to start “reclaiming the electors” and move forward with “either a do over or having a new slate of electors seated that would declare someone else the winner."

[...] Following the meeting, Vos reiterated his position that the 2020 election can’t be decertified. Vos, however, has pushed claims of widespread election fraud and was held in contempt by a judge last month for failing to turn over documents related to a Republican-led investigation he had launched himself in May 2021 into the 2020 election.

He went to several other states, including Colorado:

During the meeting, Eastman boasted about his involvement in election lawsuits in Texas, Pennsylvania, Georgia and Wisconsin and decried the “attacks” that he and others who push election conspiracies have experienced, calling it “pure evil,” according to a video of the meeting posted by FEC United.
