April 27, 2021 Dozens of congressional Democrats and Sen. Bernie Sanders on Monday urged top Biden officials to release unredacted copies of multi-billion-dollar coronavirus vaccine contracts that the Trump administration negotiated in secret with major pharmaceutical companies last year—and refused to divulge to lawmakers. In a letter (pdf) to Health and Human Services Secretary Xavier Becerra and Defense Secretary Lloyd Austin, 50 lawmakers from the House and Senate argue that public knowledge of the specific terms of the vaccine contracts "has become all the more important as manufacturers talk of boosters and seasonal immunizations, while considering 'post-pandemic' price increases." "Taxpayers should know how their funds were spent and what secret deals were reached."
