ELECTORAL COLLEGE CHALLENGE

https://crsreports.congress.gov/product/pdf/IF/IF11641

Joint Session Challenges to Electoral Vote Returns While the tellers announce the results, Members may object to the returns from any individual state as they are announced. Objections to individual state returns must be made in writing by at least one Member each of the Senate and House of Representatives. If an objection meets these requirements, the joint session recesses and the two houses separate and debate the question in their respective chambers for a maximum of two hours. The two houses then vote separately to accept or reject the objection. They then reassemble in joint session, and announce the results of their respective votes. An objection to a state’s electoral vote must be approved by both houses in order for any contested votes to be excluded.
