Democrats called on Tuesday for an investigation into U.S. President Donald Trump's daughter and top White House adviser Ivanka Trump following reports that she repeatedly used a personal email account last year for government business.

A White House review of Ivanka Trump's email found she used her personal account up to 100 times to contact other Trump administration officials, the Washington Post reported on Monday, citing people familiar with the review.

Use of a personal account for government business could potentially violate a law requiring preservation of all presidential records.
