President-elect Donald Trump has named his son-in-law, Jared Kushner, as one of his senior white house advisers.

He played a key role in the presidential campaign and his new white house job will cover both domestic and foreign policy.

Kushner, who is married to Ivanka Trump, is a property developer with a wide range of business interests.

Democrats immediately called for a review of the appointment, citing nepotism laws and potential conflicts.

Members of the house judiciary committee urged the department of justice and the office of government ethics to step in.

His appointment could potentially violate the 1967 anti-nepotism law, which bans federal authorities from giving government positions to civilian relatives in agencies under their control.

Kushner was raised in an orthodox Jewish family in New Jersey and studied as an honors student in a private yeshiva high school in 1999.
