The Senate Intelligence Committee will question Jared Kushner later this month, insiders say.

Kushner, who is a person of interest in the FBI's Russia probe, is expected to present the Committee members with documents, meet with staffers and face questions from the senators.

Early reports said that the meeting would occur mid-June, according to two insiders, but a third source said the time is still being negotiated, NBC News reported.

Probed: Presidential aide Jared Kushner will face questioning by the Senate Intelligence Committee this month as the probe into his contacts with Russia continues

Kushner is not necessarily suspected of a crime, US officials said last month, but it's believed he may have information relevant to the investigation.

However, the FBI has been looking into several aspects of Kushner's work, both on the Trump election campaign and in his role as advisor to President Donald Trump.

Those aspects include his overseeing the Trump campaign's voter data operation and his attempts to open up a secret line of communication with Vladimir Putin.

It's believed that he may have attempted to set up the line to find someone in Moscow who could buy Kushner Companies' 41-storey tower at 666 Fifth Avenue, New York, NBC reported Monday.

There are also concerns about his relationship with ex-national security advisor Michael Flynn.

Flynn was forced to step down after it emerged he had not properly briefed Vice President Mike Pence on his relationship with key Russian figures.

Kushner has himself been questioned for relationships with prominent Russians, including Sergey Gorkov, whom he met in December.

Gorkov is the chairman of Vnesheconombank, a Russian state-owned bank, and was appointed to the role by Putin.

Kushner met him as one of several representatives of major US banks and businesses, Reuters said.

Ex-FBI director James Comey was asked what he knew about Vnesheconombank during his testimony on Thursday, but said he couldn't publicly answer the question.
