In a statement Monday, the Democratic presidential nominee called the floods a crisis in need of a national response. She noted that she had asked supporters to contribute to the Red Cross to help recovery efforts for the more than 100,000 people affected by the floods.
Clinton added that she wants to make sure there is a focus on Zika prevention, so that the mosquitoes that carry the virus don't spread to Louisiana.
Republican nominee Donald Trump visited Louisiana Friday and President Barack Obama is expected Tuesday. Heavy flooding this month killed at least 13 people and displaced thousands more after water engulfed their homes.
