Inspector General Michael Horowitz told lawmakers last month that a draft of the long-awaited report was complete.

The final version is expected to be released in the coming days.

Trump, on Tuesday morning, seemed to try to cast doubt on any findings that exonerate Comey or Clinton ahead of the report’s release.

"What is taking so long with the Inspector General’s Report on Crooked Hillary and Slippery James Comey," the president tweeted. "Numerous delays. Hope Report is not being changed and made weaker! There are so many horrible things to tell, the public has the right to know. Transparency!"

The Justice Department announced the launch of its watchdog probe in January 2017, shortly before Trump's inauguration.

The internal investigation was started in response to requests from lawmakers on both sides of the aisle who sought further information on allegations that Comey broke FBI policy with his public disclosures of the Clinton email probe.

Clinton allies warmly received the launch of Horowitz’s investigation, as they blamed Comey’s public statement that the FBI was reopening its investigation into her email server for causing her poll numbers to drop days before the 2016 presidential election.

Trump fired Comey in May 2017, and has frequently criticized the ex-FBI director in the time since, saying he left the bureau’s reputation “in tatters."

Comey recently released a book. On the subsequent press tour, he defended his time as FBI director and criticized Trump as "morally unfit" for the presidency.

Sessions fired McCabe in March, saying he had leaked information to the press and misled congressional investigators. McCabe denied those accusations, saying his ouster was a political move designed to undermine Mueller's investigation into Russia's election interference and any possible coordination with the Trump campaign.
