Trump aide Meadows urges FDA's Hahn to approve vaccine by Friday

White House chief of staff Mark Meadows urged U.S. Food and Drug Administration head Stephen Hahn to authorize Pfizer Inc's COVID-19 vaccine by Friday and quipped that he should prepare to resign if not, a senior administration official said on Friday.

Meadows leaned on Hahn during a phone conversation on Friday. The official told Reuters that Meadows' comment about resigning "wasn't a red line," but was more of a quip with the intention of urging "the FDA to act quickly and get the job done and stop the delays."
