A Donald Trump science envoy just quit with an incredible secret message hidden in his letter

A State Department science envoy has publicly resigned in the wake of Donald Trump's lacklustre response to a white supremacist rally in Charlottesville, Virginia, where a woman was sadly killed.

Daniel Kammen, a professor at the University of California, Berkeley, tweeted his letter of resignation on Wednesday, condemning the President's response.

He wrote:

Particularly troubling to me is how your response to Charlottesville is consistent with a broader pattern of behaviour that enables sexism and racism, and disregards the welfare of all Americans, the global community and the planet.

People noticed that he had also spelled out a secret message to the President:

Kammen is one of seven envoys listed on the State Department website.

Julia Mason, a State Department spokesperson, said in a statement that the resignation was Kammen's "personal decision":

We appreciate his dedicated service to U.S. scientific diplomacy during his appointment working on energy efficiency and renewable energy in Africa as a Science Envoy.
