Rep. Adam Schiff, the chairman of the House Intelligence Committee, said Sunday that he believes there is still “significant evidence of collusion” linking the Russian government with President Trump’s 2016 presidential campaign, despite Special Counsel Robert Mueller's reported findings to the contrary.

“There's a difference between compelling evidence of collusion and whether the special counsel concludes that he can prove beyond a reasonable doubt the criminal charge of conspiracy,” Schiff said during an interview on ABC’s “This Week.” “I leave that decision to Bob Mueller, and I have full confidence in him.”

Attorney General William Barr on Sunday released the "principal conclusions" of Mueller's completed Russia probe in a four-page letter to lawmakers, which stated definitively that Mueller did not establish evidence that Trump's team or any associates of the Trump campaign had conspired with Russia to sway the 2016 election.

On "Fox & Friends" Monday morning, Fox News contributor Mike Huckabee said Schiff and his fellow Democrats should be blaring the hit song from the Disney film "Frozen": "Let It Go."

"Adam, you've been saying you've got evidence. Show up with a box of it and empty it on the Capitol steps or shut the heck up," Huckabee said.

He offered some advice to President Trump and Republicans as they navigate the Mueller report fallout and calls from Democrats for further collusion and obstruction investigations: "Counter-punch hard."

He noted that Democrats only control the House, while Republicans have the White House and the Senate.

"Let Lindsey Graham and the Senate Judiciary Committee go after: Who were the conspirators? Who were the ones who inside the Justice Department and FBI actually conspired to bring down this president?" Huckabee said. "Chase them to justice. Order the attorney general to do the same thing."
