President Donald Trump's son-in-law and close adviser, Jared Kushner, has used his personal email account on dozens of occasions to communicate with colleagues in the White House.

Key points: Emails included correspondence about media coverage, event planning and other subjects, Politico reports

Emails included correspondence about media coverage, event planning and other subjects, Politico reports Mr Kushner's lawyer said non-personal emails had been forwarded to the official account and preserved

Mr Kushner's lawyer said non-personal emails had been forwarded to the official account and preserved Nearly 100 emails were received or responded to from White House officials on Mr Kushner's private account

Mr Kushner either received or responded to nearly 100 emails from White House officials on the account between January and August this year, his lawyer Abbe Lowell said in a statement.

"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," Mr Lowell said.

Mr Lowell said Mr Kushner uses his official address to discuss White House business and that any non-personal emails had been forwarded to his official account and preserved.

Politico reported the emails included correspondence about media coverage, event planning and other subjects.

Mr Kushner is a senior presidential adviser and is married to Ivanka Trump.

The use of personal email to discuss government business is a politically freighted issue that factored prominently in last year's presidential election.

Hillary Clinton faced an FBI investigation for much of her unsuccessful White House bid over her use of a private email server as secretary of state under former president Barack Obama.

Former FBI director James Comey said that though Mrs Clinton and her aides were "extremely careless" in their handling of classified information, there was no evidence that anyone intended to break the law.

He recommended against criminal prosecution.

But Mr Trump repeatedly argued during the campaign that Mrs Clinton deserved to be prosecuted for mishandling classified information and had continued to suggest that even after being elected president.

He often led crowds in chants of "Lock her up!" during the campaign and vowed in October she would "be in jail" over the matter if he became president.

At a political event in Alabama on Sunday, he responded to supporter chants of "lock her up" by saying: "You've got to speak to [Attorney-General] Jeff Sessions about that."

Politico said other senior Trump aides had also used private email accounts, including former chief of staff Reince Priebus, former chief strategist Steve Bannon and economic adviser Gary Cohn.
