Rudy Giuliani, one of Trump’s attorneys, told The Associated Press on Friday that the White House hopes to get a readout of the information next week, particularly about the use of a longtime government informant who approached members of Trump’s campaign in a possible bid to glean intelligence on Russian efforts to sway the election. Trump has made unproven claims of FBI misconduct and political bias and has denounced the asset as “a spy.”

“If the spying was inappropriate, that means we may have an entirely illegitimate investigation,” Giuliani said of special counsel Robert Mueller’s probe. He then invoked the material compiled by former FBI Director James Comey before he was fired.

“Coupled with Comey’s illegally leaked memos, this means the whole thing was a mistake and should never have happened,” Giuliani said. “We’d urge the Justice Department to re-evaluate, to acknowledge they made a mistake. It’s a waste of $20 million of the taxpayers’ money. The whole thing is already a waste of money.”
