Here's who's testifying at the fourth Jan. 6 committee hearing

What to expect: Republican officials including Arizona House Speaker Rusty Bowers, Georgia Secretary of State Brad Raffensperger and his chief operating officer Gabriel Sterling will headline Tuesday's hearing as the Jan. 6 committee continues to lay out Trump's attempted strategy to overturn the election.

• The committee will also focus on how this translated into threats against election workers themselves, including former Fulton County, Ga. elections worker Shaye Moss who will testify live.
• Moss and her mother faced violent threats after Trump and his allies targeted them by name.

Catch up quick: Former President Trump and his onetime lawyer Rudy Giuliani pressured Bowers into having the Arizona legislature appoint a false slate of Trump electors, which Bowers rejected.

• Raffensperger faced fierce condemnation from Trump for refusing to budge after the president pushed him to "find 11,780 votes" — enough to overturn Biden's win in the state — in an hourlong phone call.
• Both Raffensperger and Sterling followed up with repeated and public rebuttals of Trump's claims that the election was stolen.

The big picture: At last week's hearings, two of former Vice President Pence's legal aides testified that Pence had to repeatedly resist Trump's campaign to reject electoral votes.

• Greg Jacob, Pence's former counsel, also said former Trump attorney John Eastman acknowledged before the Jan. 6 riot that former Vice President Al Gore should not have been able to overturn the 2000 election and Kamala Harris should not be able to overturn the 2024 election — even though he claimed that then-Vice President Mike Pence "should do it today."
• Since the committee's first hearing, the U.S. has been privy to explosive revelations about House Republicans who sought pardons for their roles in attempts to overturn the 2020 election, as well as recorded testimony from former Attorney General Bill Barr and Ivanka Trump.
• The House select committee has said it also plans to seek testimony from conservative activist Ginni Thomas, wife of Supreme Court Justice Clarence Thomas.
