In a controversial move, Special Counsel Jack Smith brought 37 criminal charges against former President Donald Trump over alleged mishandling of classified documents.

Yet Smith's investigation apparently isn't over, as a new report suggests that he is taking a look at the final days of Trump's presidency. 

Giuliani interviewed before grand jury

According to CNN, several witnesses have been questioned before a grand jury about a White House meeting which took place roughly six weeks after the 2020 election.

They are said to include former New York City Republican Mayor Rudy Giuliani, who served as an attorney for Trump's campaign in 2020.

Other individuals reported to be of interest to the special counsel are former National Security Advisor Michael Flynn, former Trump lawyer Sidney Powell, and former Overstock CEO Patrick Byrne.

For his part, Byrne responded to CNN's story with a mocking tweet that read, "Hi Jack Smith, I take all responsibility. Best of all, with my eidetic memory I can tell you amazing detail about it. 'Parrot-like,' say some. Call collect. I’m here to help."

Hi Jack Smith,

I take all responsibility. Best of all, with my eidetic memory I can tell you amazing detail about it. “Parrot-like,” say some.

Call collect. I’m here to help.

Smith's office leaked audio of Trump

This is not the first time that someone from Smith's office has leaked important information from his investigation of Trump.

Last month, CNN was provided with an audio recording in which Trump alleges that Chairman of the Joint Chiefs of Staff Mark Milley concocted a plan to invade Iran.

BREAKING.

Jack Smith and DOJ just leaked the Trump audio tape to CNN.

This is what DOJ thinks is their smoking gun.

Although Trump can be heard rustling papers, the former president insisted in an interview with Fox News host Bret Baier that he "didn’t have a document per se" and that the papers were actually "newspaper stories, magazine stories, and articles."

Meanwhile, CBS News cited a source as saying that the Defense Department memo on Iran is not included in "the 31 counts of willful retention of national defense information charged in special counsel Jack Smith’s indictment of the former president."

The unnamed source went on to insist that "Trump was not charged with unlawfully holding onto the Iran-related document discussed in the recording."
