Jan 6 VP Mike Pence

On Jan 6 over 115 Republican state legislators from various swing states sent a letter to their Republican leaders requesting a 10 day delay in the electoral vote count in order to investigate voting irregularities in their respective states.
VP Pence released a statement detailing his decision to act administratively, limiting his role to counting the votes.
However, he would uphold requests from both houses to jointly challenge, debate and investigate irregularities.
