A GOP lawmaker called special counsel Robert Mueller's Russia investigation a "6 million-headed monster" on Sunday.

During an interview on Fox News, Rep. Lee Zeldin, R-N.Y., said that if the Mueller team is "looking at 17 different things, well, the perception [is] they are looking at 6 million different things. And they created those clouds."

Zeldin said the scope of the Mueller probe, initially created to examine Russian interference in the 2016 election and possible collusion between Trump campaign officials and the Kremlin, has "gone so far beyond" what it was created to examine.

The Mueller inquiry has expanded to also examine whether Trump attempted to obstruct justice, and other matters, including financial crimes by former Trump campaign manager Paul Manafort and a guilty plea by former Trump lawyer Michael Cohen to fraud charges.

With there being almost 60 days until the midterm elections, the congressman said that Mueller needs to "come out and say it" if his team has not found any evidence of collusion.

Zeldin, who pushed for the Russia probe to be "refocused" and "narrowed," also knocked Jeff Sessions, who recused himself from the inquiry, saying he wished the Justice Department had an attorney general who could rein in Mueller.
