Vice President Mike Pence refused to sign on to a plan that would upend Congress certifying the election on January 6 for President-elect Joe Biden.
Earlier this week, Rep. Louie Gohmert and Arizona's slate of Republican Electoral College 'electors' filed a federal lawsuit to get a judge to say Pence has the power to pick pro-Trump electors when he presides over the Congressional session where he will finalize the presidential election results.
Politico reported late Tuesday night that a legal filing in the case indicated that Gohmert and the electors' lawyers had reached out to Pence in advance, trying to work out a deal - and it was shot down.

Pence also has the power to throw out BOTH sets of electors in any disputed state, which would leave neither man with the necessary 270 electoral votes for a victory. This would lead to a "contingent election" in the House of Representin', with each state's delegation having one total vote, and the VP having the tie-breaking vote if necessary.
Yes. The house electing the president is most likely to happen.
