BEIRUT, July 19 (Reuters) - Lebanese President Joseph Aoun will make his first trip to the White House this week to present a plan to U.S. President Donald Trump on how to disarm Iran-backed militant group Hezbollah and secure Israel's withdrawal from Lebanon.
Aoun, who served as the commander of Lebanon's U.S.-backed army before being elected president last year, is the first Lebanese head of state in nearly 20 years to visit the White House, where he will meet Trump face-to-face for the first time.
