WASHINGTON (AP) — The House panel investigating the U.S. Capitol insurrection interviewed former Secretary of State Mike Pompeo and met briefly with Pennsylvania’s Republican nominee for governor Doug Mastriano on Tuesday as it probes Donald Trump’s efforts to overturn the 2020 presidential election. Mastriano, who was outside the Capitol on Jan. 6, 2021, and helped organize efforts in Pennsylvania to submit alternate presidential electors beholden to Trump, cut his interview short without answering questions. He disputed the validity of the committee and the terms of the appearance, his attorney said. The committee is working through August, deepening its probe after blockbuster public hearings this summer that began to outline its investigation into Trump’s multi-pronged effort to reverse his election loss to Joe Biden and the subsequent storming of the Capitol on Jan. 6, 2021.
