The US Justice Department is attempting to prosecute former FBI Director James Comey for a third time, the latest case accusing him of sharing sensitive national security information in 2016, according to court documents made public on Monday.

Axar.az reports, citing Reuters, the case was revealed in a court document known as a “criminal information” that the Justice Department said it filed to stop the 10-year statute of limitations on the offense from expiring earlier this month.

The document filed in Washington federal court charges Comey with transmitting and conspiring to transmit national defense information. It alleges he shared classified information with a reporter from the New York Times in October 2016.

Comey said in a video on Instagram that “they’re back again” and referenced the Justice Department but did not provide further details. “I’m still innocent,” he added. Comey’s lawyers have already asked a judge to dismiss the case, arguing it is legally improper.

“I think he’s a dirty cop,” President Donald Trump told reporters at Joint Base Andrews, Maryland, when asked about Comey. “I don’t know much about it,” he said.
