A video of former National Security Adviser Michael Flynn encouraging “lock her up” chants at the Republican National Convention in July resurfaced Tuesday following his resignation from the White House.

“We do not need a reckless president who believes she is above the law,” Flynn told the convention crowd in Cleveland. “Lock her up, that’s right,” he said, applauding chants from the crowd about then-Democratic presidential nominee Hillary Clinton Hillary Diane Rodham ClintonBarr criticizes DOJ in speech declaring all agency power 'is invested in the attorney general' Virginia Democrat blasts Trump's 'appalling' remark about COVID-19 deaths in 'blue states' The Hill's Campaign Report: Biden asks if public can trust vaccine from Trump ahead of Election Day | Oklahoma health officials raised red flags before Trump rally MORE.

“I have called on Hillary Clinton to drop out of the race because she — she put our nation’s security at extremely high risk with her careless use of a private email server," he said.

“If I — a guy who knows this business — if I did a tenth of what she did, I would be in jail today,” he added.

Some critics of Flynn claim he broke the law by allegedly discussing Obama-era sanctions against Russia with the ambassador to Russia before Trump was sworn into office.

In a statement on his resignation, Flynn said the “fast pace of events” caused him to provide “incomplete information” to Vice President Pence and other senior officials about his communication with Russia.

The Department of Justice, then led by acting Attorney General Sally Yates, who was later fired, had reportedly warned the White House about risks Flynn posed to the administration, citing possible vulnerability to blackmail by Russia one month ago.
