"WASHINGTON — At least six of President Trump’s closest advisers occasionally used private email addresses to discuss White House matters, current and former officials said on Monday.

The disclosures came a day after news surfaced that Jared Kushner, the president’s son-in-law and adviser, used a private email account to send or receive about 100 work-related emails during the administration’s first seven months. But Mr. Kushner was not alone. Stephen K. Bannon, the former chief White House strategist, and Reince Priebus, the former chief of staff, also occasionally used private email addresses. Other advisers, including Gary D. Cohn and Stephen Miller, sent or received at least a few emails on personal accounts, officials said."

Now, you are correct that we do not know for sure what was sent on those private servers: certainly may have been party plans for all we know....but we DONT KNOW, because they have not been made public (they will eventually).

But of course as a long winded, foul mouthed supporter and love of Trump.......you do not even see the total hypocrisy at work here. I understand...it is a bit above you.
