President Donald Trump's son-in-law, Jared Kushner, is willing to co-operate with federal investigators looking into ties between Russia and the Trump campaign, his lawyer says.
The statement from Jamie Gorelick was issued on Thursday amid reports the FBI was investigating meetings Kushner had in December with Russian officials.
"Mr Kushner previously volunteered to share with Congress what he knows about these meetings. He will do the same if he is contacted in connection with any other inquiry," the statement said.
Meanwhile, the House oversight committee chairman Jason Chaffetz asked the FBI to turn over more documents about former director James Comey's interactions with the White House and Justice Department, including materials dating to 2013, when Comey was sworn in as FBI director under president Barack Obama.
The FBI and the oversight committee - as well as several other congressional panels - are looking into Russian meddling in the 2016 presidential election and possible connections between Russia and the Trump campaign.
Trump fired Comey on May 9 amid questions about the FBI's investigation, which is now being overseen by special counsel Robert Mueller, a former FBI director.
NBC News and The Washington Post first reported that the FBI's ongoing investigation includes a look at Kushner, which would place the probe inside the White House.
Kushner, a key White House adviser, had meetings in late 2016 with Russia's ambassador to the US, Sergey Kislyak, and Russian banker Sergey Gorkov.
The Post story cited anonymous "people familiar with the investigation", who said the FBI investigation did not mean Kushner was suspected of a crime.
