While the FBI and the Justice Department dig into some 650,000 emails on the computer of Huma Abedin and Anthony Weiner, the man who reported back in August that Abedin was sending classified emails to her non-secure account is explaining how the trail leads us to where we are now.

Dr. Jerome Corsi, a senior staff writer at WND.com and author of “Partners in Crime,”first reported in late August that Abedin forwarded work-related emails to her private account after scouring a report on emails from the watchdog group Judicial Watch.

“I was looking it over and it hit me, ‘She just forwarded that email to herself. Why would she do that?’ I started looking and I realized there had been about 300 emails released by Judicial Watch. I realized she forwarded 200 of them to herself,” said Corsi.

The account to which the emails were being forwarded was partially redacted, except in one email. The address was humamabedin@yahoo.com.

“As soon as I had that, I realized that she was sending many classified State Department emails offline to Yahoo, which is completely insecure. She was sending both emails she received at state.gov and emails she received at [clintonemail.com], the private server,” said Corsi.

But Abedin was not the only one sending emails to her private account.

“Hillary was sending emails from clintonemail.com to Huma Abedin at yahoo.com. They were both involved and they completely compromised the State Department security, because anybody that had the password or user name could read, in unredacted form, all these emails in real time,” said Corsi.

“Why would you go to the problem of downloading it, offloading it from the State Department computer that many emails when, if you were trying to follow the rules, you could just read them at the State Department,” said Corsi.

Corsi says there is no question there was sensitive, classified information included in these emails.

“Some of them that I found and published had been marked classified by the State Department. One in particular I remember was a Sid Blumenthal email. It came to Hillary. She sent it to Huma and Huma sent it to herself and the State Department marked it classified,” said Corsi.

He points out the classification came later but that should not matter.

“They did that retroactively afterwards, but it still should have been known to be classified by Hillary because there’s rules where documents don’t have to be marked classified to be classified when you’re at her level,” said Corsi.

Then the mystery for Corsi became how Abedin was sending emails from one account to the other.

“If Huma went to all this trouble to offload all these emails that I know about…then she probably didn’t use a State Department device. She probably used somebody else’s device,” said Corsi.

Enter Anthony Weiner, the disgraced former New York congressman, who is Abedin’s estranged husband, although they were still together during Clinton’s years at the State Department.

“It was really the FBI and the New York Police Department that decided to go knock on Weiner’s door with a search warrant. Once they found the computer and the emails, they knew they had a case. This way they didn’t have to go get permission, which they never would have been given by (FBI Director James) Comey or (Attorney General) Loretta Lynch, to continue investigating the Clinton emails,” said Corsi.

Corsi says there should be no doubt as to the criminality of Abedin and Clinton offloading emails onto Abedin’s Yahoo account.

“That’s obviously a major felony in violation of federal security laws for handling classified information. You can’t do that,” he said.

And why couldn’t they do that?

“The rules for handling classified materials is you’ve got to handle them on secured channels. You can’t let them go on an insecure channel. Clearly, sending these emails to Yahoo.com – and we know some of them had classified material because they’ve been marked classified – is a violation of the law and it doesn’t require intent,” said Corsi.

He says Clinton and Abedin could have avoided this entire scandal by establishing secure, government accounts and not sending any of it to private accounts.

“This was such an obvious violation of law and perhaps leading to an espionage case or a treason case, that when presented to Comey he really had no alternative than to go forward,” said Corsi.

He says the key to this story getting legs is the NYPD involvement in investigating Anthony Weiner’s alleged sexting of underage girls.

“With the NYPD in on it, in addition to the Department of Justice in New York, there’s no way to contain the case by saying you’re not allowed to pursue it from the FBI’s point of view. The New York Police Department said, ‘Well, we’ll pursue it,'” said Corsi.

Corsi believes this story is about to explode, as he believes Clinton and Abedin moved all the emails in preparation for a pay-to-play scheme for access to her emails.

In addition, a Tuesday release from WikiLeaks shows a March 3, 2015, email from Clinton campaign chairman John Podesta to former Clinton State Department Chief of Staff Cheryl Mills, urging a quick dispatching of unidentified emails.

“On another matter….and not to sound like Lanny, but we are going to have to dump all those emails so better to do so sooner than later,” wrote Podesta.

“This is a crime scheme that stinks. I think this WikiLeaks and this cache of 600,000 emails from the State Department, plus the other documentation we’ve gotten over time. I think this is going to be the biggest scandal in U.S. history and it’s just about to break,” said Corsi.
