Former mayor and personal lawyer to the president Rudy Giuliani delivered a stark message to special counsel Robert Mueller during a Wednesday interview on CNN.

“They should render their report,” Giuliani said of the special counsel and his team, using a poker metaphor: “Put up or shut up. The president has done anything wrong. They don’t have any evidence he did anything wrong.”

Giuliani also echoed White House press secretary Sarah Huckabee Sander’s Wednesday assertion that Trump did not command Attorney General Jeff Sessions to end the Mueller investigation in a widely circulated tweet. Giuliani and Sanders both said Trump was merely expressing himself in the tweet.

..This is a terrible situation and Attorney General Jeff Sessions should stop this Rigged Witch Hunt right now, before it continues to stain our country any further. Bob Mueller is totally conflicted, and his 17 Angry Democrats that are doing his dirty work are a disgrace to USA! — Donald J. Trump (@realDonaldTrump) August 1, 2018

Trump’s post simultaneously rebukes his attorney general for recusing himself from any matter involving Russian interference in the 2016 presidential election and calla for a direct end to the probe.

The president’s tweet comes as Muller’s team is putting Trump’s former campaign manager Paul Manafort on trial for business ties with Ukraine.
