The 35-year-old mother-of-three and her husband, Jared Kushner, have both played influential roles in Mr Trump’s administration during his first months in office.

While her two brothers, Donald Jr and Eric Trump, took control of the family business, Ms Trump followed her father to Washington.

Ms Trump was born in New York City in 1981 to Mr Trump and his first wife, Czech model Ivana Trump.

Mr Trump gave his daughter a level of authority in the family business that none of his wives ever had. She would rise to become an executive vice-president of development and acquisition along with her two brothers and is said to have handled some of the Trump Organization’s biggest deals.

Ms Trump helped expand the Trump Hotel brand abroad, handled interior design of the hotels and oversaw their international real estate brokerage, according to the Trump website.

Some ethics experts say Ms Trump’s unspecified role at the White House has raised questions about whether she is violating conflict-of-interest rules.

Ms Trump has increasingly appeared alongside her father at high-level meetings with political, business and world leaders.

Ms Trump, who appealed to working women throughout her father’s presidential campaign, has said she wants to focus on issues such as equal pay for women and paid parental leave.

Ms Trump has faced her own criticism for not publicly speaking out against some of her father’s more controversial actions.
