"I've always said that (the special council) Bob Mueller was not what the president or the White House should be concerned about – it's the southern district of New York," said Christie. Trump transition team leader, Chris Cuomo, CNN, Thursday night.
Christie, a former federal prosecutor, argued that the SDNY did not limit the scope of his investigation, unlike that of Mueller.
Christie highlighted Cohen's testimony before the House Oversight Committee on Wednesday in which Cohen said he was "in constant contact" with the SDNY "about ongoing investigations".
Christie said he was confident that the SDNY was preparing a lawsuit against those around Trump who may have committed crimes and against Trump himself for the time he left office.
"I think the prescribing time for most of these things would not work," Christie told Cuomo.
The former Republican governor added that he did not think that the SDNY had a lawsuit against the president "at the moment".
He was also asked if he was aware of any other wrongdoing or illegal actions against Trump that had not been discussed yet.
"Yes, and that's still part of the ongoing investigation in the Southern District of New York," Cohen said.
