White House senior adviser and President Donald Trump's son-in-law Jared Kushner, traveled to Iraq over the weekend on the invitation from Gen. Joseph F. Dunford Jr., the chairman of the Joint Chiefs of Staff to oversee the situation in Iraq and provide more military aide to the Iraqi forces in their fight to regain Mosul from the Islamic State, a senior administrative official said Sunday evening.

The official demanded anonymity and said he was not authorized to speak about the details of the trip or meetings by name. Kushner is expected to be back from his trip early this week.

The visit followed the deployment order of 275 soldiers from the 82nd Airborne Division to northern Iraq as the forces have been increasing their efforts in recapturing the city of Mosul, two U.S. officials confirmed to NBC News.

Trump has also sought Kushner's while dealing with foreign leaders. Kushner has played the role of a shadow diplomat to the president while advising on the country's relations with Mexico, the Middle East and Canada. Calling him a peace envoy to the Middle East, Trump told Kushner at a gala prior to his presidential inauguration, "If you can't produce peace in the Middle East, nobody can," according to the Associated Press.

Kushner has been deeply involved with several important decisions under his father-in-law's administration including the recent announcement made last week about a new unit aimed at overhauling the U.S. federal bureaucracy that will be led by Kushner. The office has been called a "SWAT team of strategic consultants." Officially the White House Office of American Innovation, it will be responsible for reformation of the Office of Veteran Affairs, focus on opioid abuse, improve the president’s infrastructure package and modernize technology.

Kushner is also expected to have major responsibilities during a meeting later this week between his father-in-law and the Chinese President Xi Jinping, which will take place at Mar-a-Lago, Trump's members-only club in Palm Beach, Florida.
