- Federal investigators have been exploring multiple angles related to Jared Kushner
- His efforts to establish a back channel to Russia is the most recent incident
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.
And a source familiar with the discussions told CNN "discussions about the timing are ongoing" to set a date for Kushner to appear.
Federal investigators have been exploring multiple angles related to Kushner, including his overseeing of the Trump campaign's voter data operation, his relationship with former national security adviser Michael Flynn and his own effort to establish a back channel with Russian President Vladimir Putin.
Federal investigators have been asking about Kushner's discussions with Sergey Gorkov, the chairman of Russia's state-owned Vnesheconombank and was appointed to the role by Putin.
Sen. Angus King, a Maine independent, asked former FBI Director James Comey on Thursday what he knew about the bank, but Comey said he could not answer that question in public.
NBC News first reported
