Chicago Mayor Rahm Emanuel (D) said in an interview broadcast Saturday night that Democrats should use their recently won House majority to scrutinize the actions of the broader Trump administration rather than setting their sights solely on President TrumpDonald John TrumpThe Hill's Morning Report - White House, Congress: Urgency of now around budget GOP presses Trump to make a deal on spending Democrats wary of handing Trump a win on infrastructure MORE.

"Don't focus immediately on Trump. ... You have something with the secretary of Labor, you have with [the Environmental Protection Agency], you have in the Interior Department, you have it at the Commerce Department, you have it at [the Department of Housing and Urban Development]. He has brought the swamp to Washington and flooded the plains, and I think [special counsel Robert] Mueller will deal with Trump," Emanuel said on CNN's "The Axe Files."

"You have an entire government that is not on its game protecting the American people," he added. "The House should focus there."

Democrats have vowed to use their majority to look into a litany of subjects involving the Trump administration and the president in particular, including his tax returns, his daughter and adviser's use of private email and his ties to Russia.

Emanuel, who worked in the Clinton and Obama administrations and served three terms in Congress, told CNN that he believes Trump is making "a big mistake" by getting directly involved in Mueller's investigation into Russian interference.

"They’re doing something we didn’t do. We actually cordoned it off, isolated it so that the president could go to work," Emanuel said, referring to investigations into then-President Clinton. "This president's decided to immerse himself in the investigation, the scandal, and not do a degree of separation and say 'I’m not going to let that affect the business that people elected me.' "

"And they're going to rue the day they didn’t do that," he added. "I think they’re making a big mistake."

Trump has consistently railed against the Mueller investigation, decrying it as a "witch hunt" and insisting he did nothing wrong.

The special counsel has implicated five former Trump associates and more than 20 Russian nationals thus far.

Prosecutors on Friday said that the president's former personal attorney, Michael Cohen, broke the law at then-candidate Trump's direction.
