In his closed interview with the staff of the Senate intelligence committee, White House senior adviser and presidential son-in-law Jared Kushner did not share the existence of his personal email account, which he has used for official business, CNN has learned.

CNN has also learned that the chair and vice chair of the committee were so unhappy that they learned about the existence of his personal email account via news reports that they wrote him a letter via his attorney Thursday instructing him to double-check that he has turned over every relevant document to the committee including those from his “‘personal email account’ described to the news media, as well as all other email accounts, messaging apps, or similar communications channels you may have used, or that may contain information relevant to our inquiry.”
