Ivanka Trump used personal email account for government work

Ivanka Trump used a personal email account to send hundreds of messages discussing official White House business last year, officials confirm.

A review into her emails revealed she had used her private address to contact government officials.

Trump sent the emails before she was briefed on the rules, her lawyer says.

In 2016, her father Donald Trump accused Hillary Clinton of putting the US "in danger" over her use of a private email while secretary of state

A US news agency reported that Trump administration official told that Trump's emails did not contain classified information, and what had occurred was basically a lack of understanding of the rules.

Trump stopped using her personal address for government correspondence after she was informed that she should not be doing so, the official said.

During his presidential campaign in 2016, Donald Trump said that Clinton's use of a private server to send official emails while in her post as secretary of state in 2009 was a scandal "bigger than Watergate".

He repeatedly criticised her conduct, calling her actions "illegal" and a threat to the security of the US.

At the time of his campaign, Trump frequently encouraged crowds at rallies to chant "lock her up" and vowed to imprison Clinton over the saga.

He also called on Russia to help locate some 30,000 emails that Clinton had not turned over to investigators after she, or her lawyers, determined it was unnecessary as they were personal messages.

Before becoming secretary of state, Clinton set up an email server at her home in Chappaqua, New York, that she used for all work and personal emails during her four years in office.

She did not use or even activate, a state government email account, which would have been hosted on servers owned and managed by the US government.

She said it was for convenience.

Clinton maintains that most of her emails from her personal account went to, or were forwarded to, people with government accounts, so they were automatically archived.

An FBI investigation concluded that Mrs Clinton should not face charges, but said she and her aides had been "extremely careless" in their handling of classified information.

Mrs Clinton has been cleared twice by the FBI over her use of a private email server while secretary of state.

It is not illegal for White House officials to use personal email accounts for government business.

However, under the Presidential Records Act and Federal Records Act, government officials must forward any official correspondence to a work account within 20 days for preservation.

If this is not done reliably, the use of private accounts can put official records beyond the reach of journalists, lawmakers and others who seek publicly available information.

There are also rules against sharing classified or privileged information on personal email accounts.
