The Senate in the wee hours of Thursday morning voted 92-7 against an objection made in joint session to certifying the Pennsylvania's Electoral College votes. The House is still debating the challenge.

Why it matters: Prior to Wednesday’s mob violence in the U.S. Capitol, over a dozen senators said they would object to certifying some states' results. But multiple senators have since withdrawn their support for those objections.

• The House and Senate voted down an objection to Arizona in the Electoral College certification process Wednesday night.
• House Republicans' objections to the electoral votes of Georgia, Michigan and Nevada failed to receive Senate support in joint session, meaning they could not be debated.

The bottom line: Electoral College votes are counted state-by-state and in alphabetical order.

• Pennsylvania is expected to be the last state to receive an objection with joint support.
