(CNN) President Donald Trump's son-in-law and White House adviser Jared Kushner is expected to meet with Senate intelligence committee staff as soon as this month, a source familiar with the matter told CNN.

It's unclear when he will meet with members of the committee, the source added, and no date has been set.

A second source told CNN that Kushner first agreed to talk to Senate intelligence staff as soon as the middle of the month, then provide records and documents to the committee before meeting with senators.
