Ted Cruz, R-Texas, right, speak after Republicans objected to certifying the Electoral College votes from Arizona, during a joint session of the House and Senate to confirm the electoral votes cast in November's election, at the Capitol, Jan 6, 2021. Hawley and Cruz led the Senate challenge to Joe Biden's victory. But the senators have largely escaped the House panel's investigation over the Capitol attack. In all, a dozen GOP senators initially planned to challenge Donald Trump's defeat. (AP Photo/Andrew Harnik, File)
