The U.S. House committee investigating the Jan. 6, 2021, incursion of the U.S. Capitol issued subpoenas on Tuesday to state Rep. Mark Finchem and Kelli Ward, the chair of the Republican Party of Arizona, asking for documents and testimony related to their efforts to upend the 2020 election results.

The subpoenas mark the latest efforts by the Select Committee to unearth the behind-the-scenes machinations, in Arizona and other states, meant to engineer a second term as president for Donald Trump despite his loss in the 2020 election.

Ward was among 11 Republicans who signed their name to a document falsely asserting they represented Arizona's official votes in the Electoral College, the mechanism set out in the U.S. Constitution that picks the president. Ward, in statements in December 2020, signaled that she expected the document to be part of a plan that could have reversed President Joe Biden's victory.
