Conservative radio personality Mark Levin during a Thursday appearance on Fox News’s “Hannity” took a jab at Eric Ciaramella and decried the National Security Council (NSC), calling it a “rat’s nest.”

Ciaramella, a White House official, is alleged to be the whistleblower behind President’s July 25 call with Ukrainian President Volodymyr Zelenskiy where Democrats accused President Trump of leveraging U.S. military aid to Ukraine for politically beneficial investigations.

But both Presidents Trump and Zelenskiy denied any wrongdoing.

President Trump said that the call was “good” and “normal,” and Zelenskiy said that there was no pressure for him to get involved in American politics.

“The whistleblower, according to a number of reports, comes off the National Security Council,” Levin told the show’s host Sean Hannity. “An Obama holdover. A Democrat. Somebody who worked with Biden. Somebody who worked with Brennan. An Obama holdover who didn’t like Trump, who met with one of the active figures in the Ukraine effort to undermine the president of the United States in 2016.”

Levin continued as he speculated the possibility that House Intelligence Committee Chairman Adam Schiff (D-Calif.) had conspired with Obama staffers who worked under the Trump administration and now work for him.

“We have two others who now were hired by Schiff, Obama holders who were in the Trump National Security Council. Now they work for Schiff and how much you want to bet one of them was the one that he colluded with,” he noted.

“And of course Schiff doesn’t know anything about it,” Levin continued. If you want to know why the president of the United States has had trouble bringing his own people in the National Security Council and getting clearances … Now you know why—because it’s a rat’s nest!”

The conservative radio host continued his barrage on Schiff, noting that his attempts to protect the “phony” whistleblower is futile since major news outlets have already reported on the issue.

“Adam Schiff, you are a key fact material witness. You hired those two Obama staffers, your staffers are one of [those who] met with the former National Security staffer to the president of the United States, you are trying to protect your staffers and protect this phony whistleblower and you are trying to protect the Democrats from 2016 and what they tried to do to candidate Trump,” Levin pointed out. “It’s all in Politico and it’s all in The New York Times even though they don’t want to admit it.”

President Trump is adamant that the whistleblower is tied to the Democratic Party and exposure of the individual would mean certain backlash for Democratic lawmakers.

“The Fake News Media knows who HE is but, being an arm of the Democrat Party, don’t want to reveal him because there would be hell to pay,” the president said on Twitter on Sunday, Nov. 3.

“My phone call was perfecto, totally appropriate,” President Trump said.

“The whistleblower should be revealed because the whistleblower gave false information,” the president said to reporters. “He made up a story.”

“They know who it is! You know who it is, you just don’t want to report it. CNN knows who it is, but you don’t want to report it. And, you know, you’d be doing the public a service if you did,” President Trump told reporters gathered on the White House lawn on Sunday.

Levin ended his remark on “Hannity” with a verbal uppercut to Schiff and Democratic lawmakers.

“This is the biggest disgusting scandal and it is all on the Democrat Party that has hijacked the impeachment process, our tax dollars, and House of Representatives to push their 2020 election,” Levin fumed. “That is what is going on, that’s it.”
