WASHINGTON, D.C.: The White House has launched an internal probe of the use of private email for official business by senior aides to President Donald Trump, news outlet Politico reported Thursday. The administration is scouring the White House server for emails to and from private email accounts of these aides, Politico said, quoting four people familiar with the probe. Politico said at least five current and former White House officials used private email to conduct government business: Trump’s son in law and adviser Jared Kushner, daughter Ivanka, economic adviser Gary Cohn, former strategic adviser Steve Bannon and former chief of staff Reince Priebus. Politico said the probe began this week after it reported private email use by Kushner. The internal probe could take weeks or even months, it said.
