The letter to Pence from the representatives of five states cited possible fraud (itemized). They requested only that Pence carve out 10 days so they could do a review of the legality of the certification.
Pence wasn't asked to do anything else ... he wasn't asked to look at anything or make any kind of determination.
Makes more sense of the riot starting within the first few states called.
So these representatives were making the request on behalf of their states? In other words, they were making the request with the authority to act on behalf of their states?
