Q: Is the Biden administration selling crude oil from the Strategic Petroleum Reserve to other countries?
A: The oil is sold to eligible companies that make the highest offers.

An executive at the German pharmaceutical company Bayer referred to mRNA vaccines used against COVID-19 as an example of innovation in biotech at the World Health Summit 2021. But a website post takes the executive’s words out of context to falsely claim he said the vaccines are gene therapy.
Sudden Arrhythmic Death Syndrome, or SADS, has been studied for decades and is caused by genetic heart problems. But social media posts suggest, with no evidence, that SADS is related to COVID-19 vaccines.
