Mnuchin Responds to Questions About Trump's Willingness to Fire Mueller.

Any decision to fire special counsel Robert Mueller is "obviously" up to President Donald Trump, Treasury Secretary Steve Mnuchin says.

"I don't have any reason to think that the president is going to do that, but that's obviously up to him," Mnuchin said Sunday on CNN's "State of the Union."

He noted that he had dinner with the president and Vice President Mike Pence at Camp David on Saturday and that he hadn't "heard anything about this, any firing."

Mueller's investigation into Russian meddling in last year’s presidential election has come under increased scrutiny from Capitol Hill conservatives after it was revealed that one of the members of his team was dismissed for sending anti-Trump text messages.

The calls to fire the former FBI director could grow louder this week after a lawyer for the Trump transition team accused Mueller of unlawfully obtaining tens of thousands of private emails during its investigation. Mueller's spokesman, though, says all the acquisitions were legal.

On Sunday, Mnuchin said, "We have got to get past this investigation."

"It's a giant distraction," he said. "Nobody has said that in any way this impacted the outcome of the election."

Mnuchin said the probe "should be over quickly, since I think there is nothing there."

"People want to focus on other things, he said.
