The Senate Intelligence Committee is expected to interview President Donald Trump's son-in-law and adviser Jared Kushner as part of a sweeping investigation into potential links between the Trump campaign and Russian officials.

Kushner volunteered to be interviewed by the committee, according to a White House official, making him the fourth member of Trump's campaign operation to come forward in the past week offering to speak with congressional investigators.

A Senate source confirmed that the interview had been offered, but said that it would not be scheduled until the committee "has received any documents or information necessary to ensure that the meeting is productive for all sides".

According to a senior congressional official, Republican committee Chairman Richard Burr, spoke to the White House counsel "some weeks ago" to warn that the committee would be seeking to speak with administration officials, including Kushner.


The White House indicated to the committee over the weekend that Kushner would be willing to participate.

According to the New York Times, Kushner met Russian Ambassador Sergey Kislyak during both the election and transition period, and later, at Kislyak's request, met Sergey Gorkov, chief of Russian government-owned Vnesheconombank.

The congressional official was not aware that Kushner had met the Russian banker.

A White House official said that Kushner was the "official primary point of contact" with foreign governments and officials during the campaign and transition period.

A spokesman for the House intelligence committee said that the committee has not decided whether it will interview Kushner.
