Do you think the release of John Eastman e-mails will show whose pants are on fire and why they are on fire?

There is nothing wrong or illegal about contesting the results of an election.  The US Constitution has a process for that to happen. And that was planned to be followed. 
The insuring riot by some of the people there stopped that  constitutional process.  
At least one member from both the House and Senate must object to the certification of each state in question.  Then there is debate about each one and perhaps going back to the state for farther verification of the accuracy of the results. 
Yes, there were members of both lined up.to object to 5 or 6 different states. MI, AZ, WI, PN GA, and NV. (IF I am remembering correctly) 

It was Biden who benefited from the Jan 6th riot not Trump. 

We know whose pants are on fire, the trick is to prove it beyond all legal possibility of doubt, because "reasonable" is open to interpretation and the SC at present largely consists of His Royal Orangeness's trained seals.
