New York (CNN Business) Former Republican Congressman and 2020 presidential hopeful Joe Walsh is slamming Fox News and conservative talk radio for their coverage of the impeachment probe of President Donald Trump.

"This is an absolute shame and I think you've got to call it out for what it is," Walsh told CNN's Brian Stelter on "Reliable Sources" Sunday. "The Americans who listen to Fox News and conservative talk radio are being lied to and manipulated every day when it comes to impeachment."

On Sunday, Walsh said he believes Trump "deserves to be impeached." But he said he's worried that not all Americans are getting the same information about the president's alleged actions.

"The vast majority of the American people understand that when it comes to Ukraine, [Trump] did something wrong,' Walsh said. "But those people who listen to the opinion shows on Fox and those people who listen to my former world, conservative talk radio, have no clue because they're being told every day: 'He's done nothing wrong' ... It's dangerous."
