NEWARK -- After more than a week on the stand and three days of cross examination, the government's chief witness in the George Washington Bridge lane closure criminal case isn't done yet.

David Wildstein is slated to take the stand again on Wednesday, when prosecutors will continue their questioning of their star witness after defense attorneys for Bill Baroni and Bridget Anne Kelly used questioning to try and tear down the character of the former Port Authority executive turned government witness.

But before prosecutors have their turn again, Wildstein pulled back the curtain on new details of the Bridgegate scandal on Tuesday.

Here are three new revelations gleaned from Wildstein's latest testimony:

1. Christie and Cuomo spoke

Within a month after the lane closings, Gov. Chris Christie discussed a plan with Gov. Andrew Cuomo of New York that he hoped would "put an end" to the increased scrutiny surrounding the four days of gridlock in Fort Lee, Wildstein testified.

"Governor Christie and Governor Cuomo discussed it," he said, referring to a plan to explain the lane closings.

"New Jersey side (would have) accepted responsibility and ... Mr. Foye would sign off on that," Wildstein said. "My understanding, at the time, was that that would put an end to this issue."

But the reports were never issued and questions surrounding the lane closings grew in intensity. Christie, a Republican, and Cuomo, a Democrat, have previously denied that such a conversation ever occurred and said they played no role in the cover-up of the lane closings.

Cuomo's office issued a statement Tuesday refuting Wildstein's claim.

2. Christie's spokesman allegedly knew of the plot

A major question throughout the Bridgegate aftermath is who knew of what, and when? Did they know the lane closures were an act of political revenge or just that access lanes to the bridge were closed?

On Tuesday, Wildstein roped another high-level Christie staffer into the category of people who he claimed knew about the cover up.

Wildstein recalled for jurors details of his Dec. 4, 2013 dinner with long-time Christie spokesman Michael Drewniak, who now works at NJ Transit. During the dinner, Wildstein brought with him a large folder to the meeting that he presented to Drewniak.

David Wildstein, former Port Authority executive and now key witness for the prosecution, testifies in federal court in Newark for the second day in the so-called Bridgegate trial.

"I wanted to show Mr. Drewniak how I had put together a file that showed the traffic story was a cover story," Wildstein said.

Wildstein's recollection of the dinner under oath contradicted a portion of Drewniak's account of the exchange that appeared in a report commissioned by the governor in the aftermath of the Bridgegate scandal fallout. He claimed he thought Wildstein was trying to explain there was actually a traffic study.

3. Christie's chief of staff got involved

Months before Christie maintained he found out about the nefarious motives behind the closures, his chief of staff pressed lawmakers and New York's governor to put the issue to rest, Wildstein testified.

Christie's then-chief of staff, Kevin O'Dowd, was "working with legislators to make the issue go away" in November 2013.

At the time, about a month after the lane closures, New Jersey lawmakers were asking questions about the gridlock in Fort Lee as news stories continued to trickle out. But, according to Wildstein, O'Dowd didn't stop there.

When lawmakers invited Port Authority officials to testify before a legislative committee - including Bill Baroni, Christie's top appointee at the Port Authority - O'Dowd hoped to prevent Patrick Foye, New York Gov. Andrew Cuomo's top appointee to the bi-state agency, from appearing before the committee.

Foye ultimately appeared and offered testimony.
