Every one of the those senators knows there was no massive election fraud - as they've all had the same access to court filed documents that I, and everyone else has - and know for a fact Trump was legitimately defeated. Rather that acknowledge such publically, they chose to participate in his scam to ingratiate themselves with Trump supporters, so as to advance their political profiles and fortunes prior to the 2024 election.
Let there be no mistake, their actions were entirely self serving and not in actuality protecting and upholding the Constitution. At minimum, all should be sanctioned by Congress, while some - Ted Cruz and Josh Hawley in particular - should be expelled from the Senate for being the ring leaders in the charade.
