I can't think of anyone. I think the best bet to get PizzaGate addressed is to get one Robert Boyce from the NYPD to live up to his promise:

“What’s in the emails is staggering and as a father, it turned my stomach,” the NYPD Chief said. “There is not going to be any Houdini-like escape from what we found. We have copies of everything. We will ship them to Wikileaks or I will personally hold my own press conference if it comes to that.”

Boyce said the Weiner emails prove the following:

Money laundering

Child exploitation

Sex crimes with minors (children)

Perjury

Pay to play through Clinton Foundation

Obstruction of justice
