Nearly a month after President Trump declared COVID-19 a national emergency, state officials are still sounding the alarm about the shortage of supplies.

There has also been a growing frustration among state leaders in trying to understand who is in charge of the federal response.

"How confident am I of federal responsibility and action?" asked Gov. Andrew Cuomo. "Not that confident."

On Thursday, Cuomo complained about the federal government's handling of the crisis. The U.S. Department of Health and Human Services confirmed that the federal stockpile is officially bare at least through this month after it was able to fulfill just a sliver of states' requests.

FEMA provided a video showing how they've chartered in more than a dozen overseas flights with supplies secured by private U.S. companies. FEMA says hald of it goes to prioritized spots, and the other half goes back to the private market, now a source of frustration for states competing with each other for the same supplies.

"I mean this was just crazy that I'm bidding on, and California is bidding on, and Florida is bidding on and we're all bidding up each other," says Cuomo.

As some state compete, others have turned to each other. California Gov. Gavin Newsom sent 500 ventilators to New York, New Jersey and Illinois.

On Long Island, Suffolk County resorted to its own devices to secure thousands of protective gowns.
