Trump's science envoy just quit. His resignation letter has a secret message calling for impeachment.

President Trump's science envoy resigned on Wednesday, leaving critics of the commander-in-chief a secret acrostic message to discover in his letter:

The first letter of each paragraph of Professor Daniel Kammen's letter spells "impeach," some readers noticed.

An energy professor at the University of California, Berkeley, Kammen cites Trump's decision to pull out of the Paris climate agreement and his failure to clearly condemn white supremacists in Charlottesville as "a broader pattern that enables sexism and racism, and disregards the welfare of young Americans, the global community, and the planet."

While he was Trump's science envoy, Kammen "focused on building capacity for renewable energies," The Sacramento Bee writes, adding that "the science envoy program draws on scientists and engineers to leverage their expertise and networks to build connections and identify opportunities for international cooperation."

Members of the President's Committee on the Arts and the Humanities also resigned with a secret message in their letter earlier this month.
