US media has reported that at least six White House officials had used private email accounts
Hillary Clinton has accused the Trump administration of 'rank hypocrisy' after details emerged of officials' use of private email accounts.
Over the weekend, it was revealed that Trump's son-in-law and senior aide Jared Kushner had used private email to "corresponded with other administration officials about White House matters".
A lawyer for Mr Kushner told Politico: "Fewer than 100 emails from January through August were either sent to or returned by Mr Kushner to colleagues in the White House from his personal email account.
"These usually forwarded news articles or political commentary and most often occurred when someone initiated the exchange by sending an email to his personal rather than his White House address."
Yesterday, The New York Times reported that at least six senior members of the administration used private email addresses to discuss White House related matters.
The US newspaper named former officials Stephen Bannon & Reince Priebus and current advisers Gary Cohn & Stephen Miller as members of the administration who had "sent or received at least a few emails on personal accounts".
The developments come despite the Trump campaign having frequently targeted Hillary Clinton in last year's election campaign for her use of a private email server.
The FBI investigation into the matter loomed over the Democrat's campaign throughout the race.

The reports about Mr Kushner yesterday prompted a congressional oversight committee to write to the White House, asking them to disclose any details of private email use by officials.
Hillary Clinton, meanwhile, hit out at the Trump administration following the latest developments & their repeated criticism of her own email controversy.
She acknowledged her use of the private email server was a 'dumb mistake' - but added it was a 'dumber scandal'.
Speaking to SiriusXM, the former of US secretary of state argued: "The hypocrisy of this administration, who knew there was no real scandal, who knew that there was no basis for all their hyperventilating...
"It's just the height of hypocrisy. If they were sincere about [it], I think you'd have Republican members of Congress calling for an investigation. I haven't heard that."
