Jared Kushner to speak to Senate committee over his meeting with Russian ambassador Sergei Kislyak
President’s son-in-law has become part of the investigation
Ms Hicks also said Mr Kushner “isn’t trying to hide anything” and would speak to the panel.
A White House official also said that Mr Kushner had already "volunteered" to speak to the Senate Intelligence Committee and had "not heard back yet".
FBI Director James Comey confirmed the investigation of Trump aides last week at a Senate hearing.
Following the intelligence reports, at least four congressional committees are looking into the extent of alleged collusion with Russia and what impact, if any, it had on the election.
The New York Times reported that later in December last year, Mr Kislyak requested a second meeting with Mr Kushner, and the then-newspaper editor and real estate developer asked a deputy to attend.
At Mr Kislyak’s request, Mr Kushner then met Sergei Gorkov, head of Vnesheconombank, which was also sanctioned by the European Union after Russia invaded Ukraine.
