Donald Trump is the son-in-law of Jared Kushner used a private email account to conduct official White House business, his lawyer said.
Mr. Kushner is a top advisor to the presidency and is married to Ivanka Trump.
His lawyer has confirmed the existence of the account of personal e-mail in a statement released Sunday.
During his campaign, Mr. Trump repeatedly criticized rival Hillary Clinton for using a personal email account while secretary of state.
The president often encouraged the crowds at events to sing the “lock”, and vowed to imprison Ms. Clinton about the concerns that she may have mishandled classified information. An investigation on the case has been closed without charges.

Dozens of emails were exchanged between Mr. Kushner and other White House officials on issues such as media coverage and event planning, according to Politico, which first published the story.
There has been no indication that Mr. Kushner shared classified or protected information through her e-mail account.
“Mr. Kushner uses her White House email address for the conduct of White House business,” his lawyer, Abbe Lowell, said in a statement.
“Less than a hundred emails from January until the month of August have been sent to or returned by Mr. Kushner to his colleagues in the White House from his personal email account.”
“These usually passed on news articles or political commentary, and most often occurred when someone initiated the exchange by sending an email to his personal, rather than the White House, the address.”
Federal regulations specify the manner in which records related to the president and other government activities should be maintained.
The use of private accounts can put on official documents beyond the scope of journalists, legislators, and other persons seeking information accessible to the public.
