WASHINGTON: A science advocacy group on Friday lambasted the US Environmental Protection Agency (EPA) for firing five “whistleblowers” who signed a public letter critical of the Trump administration. “The EPA fired five whistleblowers who signed the EPA Declaration of Dissent, and issued a Notice of Removal for an additional four employees,” according to a statement from Stand Up for Science, a non-profit organization created in response to US President Donald Trump’s cuts to federal research funding and other policies.
