President Donald Trump’s lawyer Rudy Giuliani on Sunday said the White House won’t start firing people to kill special counsel Robert Mueller’s Russia investigation because it would raise parallels to “Watergate,” and accused the FBI of criminal behavior.

“The president’s not going to fire them because that would be playing into the hands, of playing the victim, Watergate,” Giuliani said on “Fox News Sunday.” “They’re the Watergate. They’re the people who have committed the crimes.”

The former New York City mayor said revelations that the Obama administration’s FBI used an informant to talk to people on the Trump campaign in the summer of 2016 discredits Mueller’s probe into Russian interference in the election and any collusion on the part of campaign associates.

“What we have to do is go to court and seek protection from the court,” he said on the program. “If we have to do that, our first thing is we sure as heck are not going to testify unless this is all straightened out, unless we learn the basis of that Russian investigation.”

But he said, “They’re not going to tell us because the basis is going to turn out to when it spreads to Trump to be unethical or illegal.”

In an appearance on CNN, Giuliani continued to tout his claims that the presence of an FBI informant makes Mueller’s probe illegitimate.

“We’re more convinced, as we see it, that this is a rigged investigation. Now we have this whole new ‘Spygate’ thing thrown on top of already legitimate questions,” he said on “State of the Union,” using Trump’s moniker for the scandal.

Giuliani was referring to President Richard Nixon’s firing of special counsel Archibald Cox in October 1973 during the Watergate investigation after two top officials in the Department of Justice resigned instead of carrying out his order.

Nixon’s move is known to history as the “Saturday Night Massacre.”

Attorney General Jeff Sessions has recused himself from Mueller’s probe.

Deputy Attorney General Rod Rosenstein is overseeing the investigation.
