Rep. David Cicilline (D-R.I.) on Friday shared a threatening voicemail he said he received after speaking out about special counsel Robert Mueller's report.

"Hi, just a message for the corrupt, treasonous, piece of shit, f---ing Congressman Cicilline," the voicemail shared on Twitter states. "F--- you, you traitor. I cannot wait until you're rotting in a cell in Gitmo. F--- you."

Cicilline wrote on Twitter that he received this voicemail after he spoke out on the Mueller report.

"I'm not scared," the lawmaker said. "Our democracy is too important to let the bullies win."

Cicilline, a member of the House Judiciary Committee, on Thursday released a statement calling the report a "damning document" that was negative for President Trump.

"As I continue to read the entire report, it is already evident to me that this is a damning document that outlines a series of misdeeds conducted by the President and his associates," Cicilline wrote of the redacted report. "In light of his misleading attempt to spin the report this morning, it's clear that the only reason Attorney General Barr has for keeping the full report from Congress is to protect the President."

House Judiciary Committee Chairman Jerrold Nadler (D-N.Y.) on Friday issued a subpoena to compel the Department of Justice to turn over Mueller's full report without redactions, including classified information.

"No one is above the law. The American people deserve to know whether their President committed wrongdoing," Cicilline wrote. "This report makes clear that Congress has a responsibility to answer that question."

The Department of Justice on Thursday released a redacted version of Mueller's report looking at Russian interference in the 2016 election.
