Jared Kushner is reported to be facing an increased degree of scrutiny from the ongoing probe into his father's ties with Russia.
The senior White House advisor reportedly failed to hand over a key document about a 'Russian backdoor overture'
Reports have been circulating since Friday in American news outlets of Aleksander Torshin, a Russian banker with close ties to Vladimir Putin, attempting to broker a meeting between the Russian President and the then-presidential candidate.
Senate Judiciary Committee leaders say Kushner - who is married to Donald Trump's elder daughter Ivanka - did not disclose this information to investigators in the inquiry.
They said the contact had come to Kushner's attention through an aide named Rick Dearborn, and after an email chain, his lawyers say he did not allow the meeting to proceed.
The Senior White House advisor has increasingly become a key focus of the probe, centring on claims of his evasiveness.
In July, Kushner admitted to having met four Russians during the presidential campaign and the transition period, which he had not acknowledged when applying for his security clearance.
