NBC News pressed for the Trump campaign to meet specific health and safety protocols, according to a person familiar with the matter. At the network’s insistence, this person says, the National Institutes of Health had to run tests, review recent medical data and determine “with a high degree of confidence” that President Trump was no longer shedding infectious virus. NBC News said Wednesday that Dr. Clifford Lane, Clinical Director at NIH, and Dr. Anthony Fauci reviewed the president’s recent medical data as part of the process.
