Who is in Charge of the Impeachment Trial?

Who is in Charge of the Senates Presidential Impeachment Trial?
(It is not the president being impeached)!
I have checked our ‘Constitution’, by-laws, each signer of the constitution, and any add-ons,
I can tell you beyond any shadow of doubt, that it is not the president being impeached’!
It is not any senators; it is the (Chief Justice of the Supreme Court).

Sen. Mitch McConnell supposes that it’s up to him to determine the way
(president donald trump’s impeachment trial), will proceed in the Senate.

“Everything I do during this,
I’m coordinating with the White House counsel,”

he declared last week, and pledged to use his power as majority leader
to assure trump’s triumphant acquittal.

But McConnell is wrong:

It is Chief Justice John Roberts, not the majority leader, who will be making all the key decisions.
This is the plain meaning of the
Senate’s “Rules of Procedure and Practice”
currently in force for the conduct of impeachments.
These rules explicitly provide that the chief justice “shall” preside over the trial, that it is the
“Presiding Officer”
Who
“shall direct all forms of the proceedings,”
and that he may
“rule on all questions of evidence including,
but not limited to, questions of relevancy, materiality, and redundancy of evidence.”
Jurisprudence
Who’s Really in Charge of the Senate Impeachment Trial?
Mitch McConnell thinks he’s calling the shots.
He’s wrong.
