Mueller must indict Trump rather than send a report to Congress

Mueller must indict Trump rather than send a report to Congress because the members of the House of Representatives were all elected during the null-and-void election of 2016.  The Republican majority benefitted from the Trump treasonous conspiracy with Russia to interfere with The United States Election of 2016. An Impeachment would need to have a two thirds vote from the House of Representatives for it to go ahead.  A finding of impeachable offenses on Trumps part would mean that the House Representatives would be declaring their election a direct consequence of the illegal actions of Trump conspiring with the Russians which would mean the House was illegally elected also. This would equally apply to 1/3 of the Senate also, the fractions of the Senate that was elected in 2016. These bodies would be adjudicating their own legitimacy while they were adjudicating Trump's Treasonous Conspiracy with Putin and Russia. 

Only by inditing the Conspirators can justice be impartially applied to them, with full constitutional protections, and only judged by an independent body without self-interest in the conclusion.

2016 Election is null and void

Several people in the Trump campaign failed to register as agents of a foreign government. They were therefore secret agents of a foreign government. Secret agents are spies. Trump and many of his campaign workers conspired with Russian officials, from Putin on down to Kisliak, the lawyer Jr. met with, etc. The unavoidable conclusion is they all committed treason to get Trump elected. The election is therefore null and void and we must redo the election of 2016 beginning with the primaries for every office that was filled.
