 Reports of some recent shark activity in the waters off the coast of various locations across the U.S. In Texas, four people were hurt this week by shark attacks, with one swimmer taken to the hospital. ABC's Trevor Ault has more from New York. Here in New York, after there were so many shark sightings last year, the lifeguards out on the beaches here are now equipped with drones so they can keep an eye out for sharks and also keep an eye out for any swimmers who might need help if they encounter one. In Florida, there have been multiple shark sightings and at least four attacks.
