New details are emerging in the superseding indictment of senior Senator Bob Menendez filed Thursday in Manhattan.

The Southern District of New York charged Menendez with being an unregistered agent of the Egyptian government.

The indictment alleges Menendez provided sensitive U.S. government information and took other steps that secretly aided the government of Egypt.

Menendez has denied these new allegations, but as senior correspondent Brenda Flanagan reports, the new charges describe how Menendez met with Egyptian officials regarding an American citizen injured in an airstrike to help smooth things out.

All while Congress was attempting to block aid to the country.

Federal prosecutors slapped another charge on Senator Bob Menendez, alleging he illegally acted as an unregistered foreign agent of the Egyptian government.

The superseding indictment adds some disturbing new details to sweeping accusations that Menendez and his wife, Nadine, accepted cash gold bars and a luxury car in return for his influence as chair of the Senate Foreign Relations Committee.

It's plain law that public officials like Senator Menendez are not allowed to be registered as a for on behalf of a foreign principal.

They can't do business in that fashion, former prosecutor Chris Commission says.

This fourth count fleshes out the indictment.

It describes how Menendez met with Egyptian officials to discuss an American citizen widely identified as April Crawley.

She was badly injured when her tourist group in Egypt got mistakenly hit by an airstrike.

American made Apache helicopters flown by the Egyptian military.

11 people died and Congress retaliated by blocking millions in military aid to Egypt.

Former Congressman Tom Malinowski served on the Egypt Human Rights Caucus then.

We were successful in restricting some of the aid to try to force the Egyptians to pay her the compensation that she deserved.

But Egyptian officials reached out to Menendez.

The indictment says texting New Jersey businessman while Hannah if Menendez helped resolve the matter, he will sit very comfortably.

To which Hannah replied, Orders.

Consider it done.

Nadine Menendez forwarded the text to her husband and then deleted the messages.

He was having those conversations while the rest of us were talking to April Crawley, the American woman who was the victim of this, that he was talking to the Egyptian government about how to protect them from the criticism.

That doesn't sit well with me.

Grumet John thinks the prosecutors will argue.

Menendez His actions go beyond the senator's regular job.

Look at the level of the abuse of public trust to personally enrich themselves.

No, it knew no bounds.

It didn't matter that this was adverse to an American citizen.

But Menendez has defiantly resisted a chorus of calls for his resignation.

I have always worked to hold accountable those countries, including Egypt, for human rights abuses, repression of its citizenry, civil society and more.

He said yesterday the facts haven't changed.

Only a new charge.

It's an attempt to wear someone down.

And I will not succumb to this tactic.

But some former supporters looking at the stash uncovered by FBI agents feel betrayed.

At the end of the day, I saw money go to parties, so I'm very sad.

Ahmed Mohammed fled political persecution in Egypt to settle in New Jersey and used to consider Menendez an ally.

But Menendez did a very hard thing that he held within to take money and to oppress people.

So this is against American values.

This is I mean, Americans know this is an American principle.

A former State Department diplomat notes public servants must be held to a higher ethical standard.

It needs to be a avoiding the appearance of impropriety.

And certainly all indications are that the senator has not, unfortunately met that standard.

With his Senate colleagues now discussing whether Menendez should be expelled.

New Jersey senior senator seems grimly determined to hang on.
