Members of Congress, advocacy groups, and a former administration official say Operation Warp Speed should release its vaccine contracts with pharmaceutical companies, following an NPR report that the Trump administration awarded billions of dollars through a third party, bypassing the usual contracting process.

Eli Zupnick, a spokesman for the advocacy group Accountable Pharma, said his organization has sent several rounds of public records requests to HHS and the Department of Defense, asking for contracts related to Operation Warp Speed.
