The National Oceanic and Atmospheric Administrations chief scientist will investigate whether the agencys response to Donald Trump s misleading tweets about Hurricane Dorian violated NOAA policy, according to an email obtained by the Washington Post.

In the email, acting chief scientist Craig McLean reportedly told NOAA staff hell investigate why the agency issued a press release on Friday corroborating false claims by Trump, who repeatedly said Alabama would be hit much harder by Hurricane Dorian than anticipated. On Monday, The New York Times revealed that the press release was issued after Secretary of Commerce Wilbur L. Ross Jr. threatened to fire top NOAA employees following a tweet from its Birmingham office contradicting Trump.

[T]he content of this press release is very concerning as it compromises the ability of NOAA to convey life-saving information necessary to avoid substantial and specific danger to public health and safety, McLean reportedly wrote in the email.
