"Mr Kushner participated in thousands of calls in this time period. He has no recollection of the calls as described. We have asked (Reuters) for the dates of such alleged calls so we may look into it and respond, but we have not received such information," Jamie Gorelick said.
The Washington Post and NBC News reported this week that Kushner was under FBI scrutiny over his contacts with Russia.
A law enforcement official told Reuters that while the bureau is investigating his Russian contacts, the White House official is not currently a target of the investigation.
