Donald Trump has taken to Twitter to accuse America's Food and Drug Administration (FDA) of deliberately delaying Covid-19 vaccine trials until after November's Presidential election.
The US President wrote the "deep state, or whoever" at the FDA is "making it very difficult for drug companies to get people in order to test the vaccines and therapeutics".
"Obviously, they are hoping to delay the answer until after November 3rd. Must focus on speed, and saving lives!"
House of Representatives Speaker Nancy Pelosi called Trump's statement "very dangerous".
