 The pier that was built by the U.S. military to bring aid to Gaza has been removed due to weather to protect it, and the U.S. is considering not reinstalling it unless the aid begins flowing out into the population again. About half a million people are at risk of famine in Gaza. More than 96% of Gazans are food insecure. ABC News chief global affairs correspondent Martha Raddatz visited that floating pier when it was on the water and shared her experience with Brad Mielke as she first sat on that boat approaching the structure.
