Hawley vows to challenge Biden electors, forcing vote McConnell hoped to avoid

Prior to Hawley’s pronouncement, all eyes had been on Sen.-elect Tommy Tuberville (R-Ala.), who had signaled his willingness to support a challenge to Biden’s victory. Trump had praised Tuberville and blasted other Republicans as “weak,” threatening to end the political career of Sen. John Thune (R-S.D.), who told reporters that any challenges were doomed to defeat.

The traditional rules of the Jan. 6 session — a joint meeting of the House and Senate — require a single House member and senator to join together to lodge a challenge. If they do, the branches are required to separate and debate the challenge before resuming the joint session.

Dozens of House Republicans have already pledged to challenge the results but had yet to secure unequivocal support from a senator.

The rules that govern those challenges are due to be adopted on Jan. 3. But at least some Republicans have endorsed a legal effort to scrap the rules altogether and empower Vice President Mike Pence, who will preside over the session, to unilaterally introduce electors backing Trump.

House Democrats have challenged the results of the 2000, 2004 and 2016 elections, but only after the 2004 election did a senator — California’s Barbara Boxer — join in the challenge. That year, Democrats objected to Ohio’s electoral votes, which forced a two-hour debate and was ultimately defeated by a wide margin.
