(CNN) President Donald Trump on Saturday accused, without providing any evidence, the US Food and Drug Administration of deliberately delaying coronavirus vaccine trials, pressuring the man he had picked to head the agency. Trump ended his tweet by tagging the Twitter account of FDA Commissioner Dr. Stephen Hahn, who he nominated last year to take up the role. Hahn assured Americans earlier this month that the agency "will not cut corners" to approve a vaccine. Trump has promised that a vaccine would be available by the end of the year, though vaccinologists told CNN that timeline is unrealistic. The FDA doesn't conduct the trials itself, but instead oversees the people who do , according to the agency.
