The conversation with Kushner was heavily focused on former National Security Adviser Lt. General Michael Flynn, in addition to other questions about Kushner's activities during the campaign, sources confirm to ABC News. Those aforementioned activities include his participation in the infamous Trump Tower meeting with Donald Trump Jr. and Paul Manafort, as well as other meetings he took during the campaign and transition period.

An attorney for Mr. Kushner, Abbe Lowell told ABC News Wednesday, "Mr. Kushner has voluntarily cooperated with all relevant inquiries and will continue to do so."
