Former U.S. Attorney Joe diGenova is optimistic about the investigation into the origins of the Russia probe, noting that the process is moving at “lightning speed.”

Along with his wife and partner, Victoria Toensing, diGenova spoke with Fox Business Network’s Lou Dobbs about U.S. Attorney John Durham and his examination of the FBI’s Russia inquiry which is now a criminal investigation.

“Is there any reason for me, for everyone watching, for everyone listening to you and Victoria to think that we’re actually going to see the scoundrels who made up the leadership of the Department of Justice and the FBI are going to be held accountable?” Dobbs asked on “Lou Dobbs Tonight” Wednesday.

“Yes,” diGenova replied.

“And by any traditional standard this thing is moving at lightning speed,” he added.

“In a very short period of time John Durham has interviewed, I understand, dozens of potential witnesses and has moved into setting up a grand jury. So it’s going to happen,” deGenova continued, adding that people need to be “reasonable” in their expectations of potential criminal charges as the process moves forward.

“This is a very difficult area of the law, to bring criminal charges where government officials are claiming that they acted in good faith,” he explained.

“We may see some initial cases which are not brought. But eventually, Durham is focused on a very large criminal conspiracy involving defrauding the United States government of faithful service of these agencies,” diGenova told Dobbs, adding that the Connecticut federal prosecutor will ultimately “get to the point of bringing charges.”

“It isn’t going to happen quickly. And there are going to be some instances where he isn’t going to have enough evidence to charge even some pretty big people initially. But some of these players will be involved in more than one series of criminal investigations. So if they get a pass in one instance, they may not get it in another,” diGenova said.

“It’s going to be rough. It’s going to be difficult, but believe me, Bill Barr is not going to pass up the opportunity to do the right thing,” he added, referring to the Attorney General who named Durham to the probe.

“And how long did it take Mueller to find nothing? Two and a half years,” Toensing interjected, referring to former special counsel Robert Mueller and his investigation into alleged Russian collusion and President Donald Trump’s 2016 campaign.

It was reported that Durham’s investigation in recent days had reached out to Maltese academic Joseph Mifsud, who had said he had damaging information about Hillary Clinton in a conversation with former Trump campaign adviser George Papadopoulos.
