President Donald Trump’s son-in-law and Senior Adviser, Jared Kushner, is under FBI scrutiny as part of the Russia investigation.
Reports say investigators believe he has relevant information, but he is not necessarily suspected of a crime.
The FBI is looking into potential Russian meddling in the 2016 election and links with President Trump’s campaign. The President denies any collusion.
Kushner’s lawyer said his client would co-operate with any inquiry.
President Trump has described the situation as “The Single greatest witch hunt of a politician in American History”.
US Intelligence Agencies believe Moscow tried to tip the election in favour of the republican, who beat his democratic rival Hillary Clinton
Former FBI Chief Robert Mueller last week was named by the justice department as special counsel to oversee the Russia inquiry.
Congress is also looking into Russia’s alleged meddling in the 2016 election and any trump campaign ties.
Kushner has already agreed to discuss his Russian contacts with the senate intelligence committee.
