CNN Paris correspondent Melissa Bell reports from the water as Paris mayor Anne Hidalgo delivers on her promise to swim in the River Seine in an effort to alleviate concerns around the river's suitability for swimming events during the Paris Olympics, despite a 1.4 billion Euro ($1.5 billion USD) cleanup plan ahead of the Games. The Opening Ceremony will take place on the river on July 26, if currents are not too strong. https://cnn.it/468bNmG | CNN
