Jared Kushner, a son-in-law and senior adviser of U.S. President Donald Trump, visited Iraq with the highest-ranking Pentagon general.
The April 3 visit came as Iraqi government forces, backed by U.S. air strikes, battle to retake the northern city of Mosul from Islamic State (IS) militants.
Iraqi Prime Minister Haider al-Abadi's office said the premier met with Kushner as well as General Joseph Dunford, chairman of the U.S. Joint Chiefs of Staff, and White House homeland security adviser Tom Bossert.
Abadi's office said in a statement that they discussed "the battle of Mosul and the international coalition's support for Iraq and the training and arming of Iraqi forces in addition to the [issue] of displaced people."
Dunford said he invited Kushner to accompany him so they could hear "first-hand and unfiltered" from military advisers about the situation on the ground and interact with U.S. forces.
Kushner, who has no previous diplomatic or government experience, has been involved in selecting presidential staff members and has advised on relations with the Middle East, Canada, and Mexico.
Kushner is married to Trump's oldest daughter, Ivanka.
