Eh, Trump knew Pence was going to side with the establishment. Afterall, HE IS ESTABLISHMENT. He knew the ANTIFA's plans to storm the Capitol. He knew this would unlock the Insurrection Act. He knew the more people he had in DC on Jan 6th, the more NG could be justifiably sent to the Capitol. And after all of this they frantically ran for the impeachment. Trump didn't make so many enemies with the DS without some powerful friends backing him.

EDIT: All Jan 6th did was seal the deal for committing treason.
