President Trump is set to ask Congress for “substantial new resources” to end the spread of HIV in the U.S., one of his top health officials said Wednesday.

Dr. Brett Giroir, the assistant secretary for health, told an audience at the American Public Health Association meeting Wednesday that the president’s budget would request more funding for agencies such as the Centers for Disease Control and Prevention, the National Institutes of Health, and the Health Resources and Services Administration in order to tackle HIV.
