Former FBI Director James Comey took a swing at the “weasels and liars” who are cheering on the expected release of a congressional memo alleging bias among the FBI’s top officials while applauding his former agency for taking a stand against it.

“All should appreciate the FBI speaking up. I wish more of our leaders would,” Comey tweeted Thursday. “But take heart: American history shows that, in the long run, weasels and liars never hold the field, so long as good people stand up. Not a lot of schools or streets named for Joe McCarthy.”

The tweet came just hours after the FBI Agents Association defended current FBI Director Christopher Wray’s decision to stand up against President Trump’s expected decision to release the bombshell memo.

The GOP-led House Intelligence Committee voted on Monday to make the memo public despite concerns from Wray and other intelligence officials who argue that the memo should not be released due to sensitive information that could pose a threat to national security.

Since the committee vote, the White House has signaled their intent to release the memo after undergoing a review process.

Comey was fired from his position as director of the FBI in May by President Trump, a move that has raised red flags in special counsel Robert Mueller’s Russia probe on whether it amounts to obstruction of justice by the president.

Since his dismissal, he has sent a flurry of snarky tweets aimed at the administration.
