Biden promises aid and support during visit to tornado-hit Mississippi town.

President Biden mistakenly referred to Rolling Fork, Mississippi, as "Rolling Stone" during a speech on Friday, following the devastating tornadoes that hit the region last week. The tornadoes killed at least 25 people and destroyed many businesses and residential areas. Biden promised to help with recovery efforts and ensure that the affected people have a place to sleep and food to eat. Former Rolling Fork Mayor Fred Miller said that most of the town's businesses were destroyed, and people are still trapped in some eateries.
