Anecdotally, there are wide differences, and they do not appear to follow discernible political or geographic lines. Democratic-leaning Massachusetts, which has had a serious outbreak in Boston, has received 17 percent of the protective gear it requested, according to state leaders. Maine requested a half-million N95 specialized protective masks and received 25,558 — about 5 percent of what it sought. The shipment delivered to Colorado — 49,000 N95 masks, 115,000 surgical masks and other supplies — would be “enough for only one full day of statewide operations,” Rep. Scott R. Tipton (R-Colo.) told the White House in a letter several days ago.

The Federal Emergency Management Agency inherited control of the stockpile barely a week ago from HHS. Lizzie Litzow, a FEMA spokeswoman, acknowledged the agency maintains a spreadsheet tracking each state’s request and shipments. Litzow declined repeated requests to release the details, saying the numbers are in flux.

Florida has been an exception in its dealings with the stockpile: The state submitted a request on March 11 for 430,000 surgical masks, 180,000 N95 respirators, 82,000 face shields and 238,000 gloves, among other supplies — and received a shipment with everything three days later, according to figures from the state’s Division of Emergency Management. It received an identical shipment on March 23, according to the division, and is awaiting a third.
