The vigil, organized by National Nurses United, was one of many held nationwide to honor Pretti's life and service as a healthcare worker. "We're here celebrating his life as an ICU nurse and someone who put his life on the line to help others," said Kerry Hewitt, a cardiovascular ICU nurse at St. Joseph's Hospital. President Donald Trump offered condolences to Pretti's family and promised a thorough investigation into the incident. And it's a very sad situation," Trump said. Trump recently spoke with Minnesota Governor Tim Walz about the situation, saying they "seemed to be on a similar wavelength."
