Deputy Attorney General Rod Rosenstein forcefully defended the special counsel’s investigation into Russian meddling in the 2016 election in a new interview Wednesday, calling the probe “appropriate” and “independent.”

People should have faith in whatever the findings of Robert Mueller’s investigation are, Rosenstein told The Wall Street Journal in an interview published Wednesday, as he waved off Republican and conservative attacks of the probe.

“People are entitled to be frustrated, I can accept that,” he said. “But at the end of the day, the public will have confidence that the cases we brought were warranted by the evidence, and that it was an appropriate use of resources.”

The investigation has already revealed that Russians attempted to interfere in the 2016 election, he said.

“I committed I would ensure the investigation was appropriate and independent and reached the right result, whatever it may be,” Rosenstein said. “I believe I have been faithful to that.”

His comments are a sharp contrast to President Trump — who has repeatedly called Mueller’s investigation a “witch hunt” and “rigged.”

There was widespread speculation last month that Rosenstein’s days at the Justice Department were numbered following reports that he mentioned wearing a wire to record Trump and recruited cabinet members to boot him from office in 2017. Rosenstein staunchly denied this.

President Trump announced last week he had no plans to fire the embattled Deputy AG.

“The president knows that I am prepared to do this job as long as he wants me to do this job,” Rosenstein said. “You serve at the pleasure of the president, and there’s never been any ambiguity about that in my mind.”
