Former Trump national security advisor Michael Flynn appears before Fulton County grand jury

Michael Flynn and his lawyers put up quite a legal battle to keep from appearing before the Fulton County special grand jury investigating possible illegal interference in the 2020 election by then-President Donald Trump and others. The former national security advisor to Trump legally tried to quash the summons for him to testify in Florida, but an appeals court this week rejected his arguments. That set the stage for his testimony on Thursday.

ATLANTA - Security was on high alert for Michael Flynn's appearance before and after his testimony before and after the Fulton County grand jury investigating former President Donald Trump and others.

We watched at 7:45 a.m. as bomb sniffing dogs made their way around the courthouse. Sheriff’s deputies patrolled on foot, by car and motorcycle.

Michael Flynn is the latest high profile Republican operative to find themselves testifying before the Fulton County grand jury investigating whether former president Donald Trump and others broke the law during the 2020 election.

Flynn, is a former Army lieutenant general and National Security Advisor under Trump. He pleaded guilty to making false statements to the FBI during Special Counsel Robert Mueller’s investigation into Russian interference in the 2016 election.

In November 2020, Trump granted Flynn a full pardon.

In June, Flynn repeatedly pleaded the fifth when questioned by the January 6th committee about his role - if any - in the assault on the nation's capitol.

"Well he's almost certainly going to take the fifth for every question asked," Georgia State law professor Clark Cunningham told us.

Cunningham has closely followed the grand jury proceedings. He expects Flynn to plead the fifth in Fulton County, as is his right. Cunningham says Fulton County prosecutors want to know about that pardon Flynn received from the president and comments Flynn made after the election regarding martial law, and the president’s ability to seize voting machines.

"He seems a more key witness for a federal grand jury looking into January 6th. So, I'm not sure if he is as important as some of these other witnesses in terms of what is happening in Georgia," said Cunningham.

Flynn was inside the courthouse less than an hour and a half. He had nothing to say to reporters when he left.
