Conservative talk show host Sean Hannity ripped special counsel Robert MuellerRobert Swan MuellerSasse: US should applaud choice of Mueller to lead Russia probe MORE late Tuesday, saying his career has been "anything but impeccable."
"Well, we’ve been doing some digging and we found some things you need to know about," Hannity added.
Hannity made a reference to Mueller's involvement in the Whitey Bulger case in Boston in the 1980s. Mueller handled the case, in which four men were wrongfully found guilty of murder, while he was an assistant U.S. attorney.
“Robert Mueller was the U.S. attorney in charge while these men were rotting in prison while certain agents in the FBI under Mueller covered up the truth,” Hannity said.
“They’ve never investigated him! They’re actually just lying! It’s their talking point!” he said.
“All of the information we’re telling you about is right there, right in front of the liberal mainstream media, in their faces, but they purposefully ignore it because their 'destroy Trump' agenda, that goes above all else.”
The host's comments come as President TrumpDonald John TrumpKoch-backed group launches six-figure ad buy against Heitkamp Anti-abortion Dem wins primary fight Lipinski holds slim lead in tough Illinois primary fight MORE has ramped up his attacks on Mueller in recent days, stoking speculation the president may move to fire the special counsel.
Trump ignored legal advice last week and mentioned Mueller by name in a tweet referencing the federal probe into alleged ties between the Trump campaign and Russian election meddling.
The Mueller probe should never have been started in that there was no collusion and there was no crime. It was based on fraudulent activities and a Fake Dossier paid for by Crooked Hillary and the DNC, and improperly used in FISA COURT for surveillance of my campaign. WITCH HUNT!

Speculation has swirled that the president could sit down with Mueller as a part of the investigation in the near future.
CNN reported on Monday that attorneys for Trump and Mueller's team of investigators met to go over potential topics investigators could ask the president about.
