In a resignation letter dated Wednesday, former Science Envoy for the State Department Daniel Kammen cited his disagreement with President Donald Trump's "failure to condemn white supremacists" and efforts to "undermine energy and environmental research" as the reason he could no longer hold the position.
"Acts and words matter," Kammen wrote. "To continue in my role in your administration would be inconsistent with the principles of the United States Oath of Allegiance to which I adhere."
Upon Kammen's publishing of the missive to Twitter, however, many were quick to point out a more subtle message.
The first letter of each paragraph appeared to spell out one word: "impeach."
The incident seems to be fully intentional, as Kammen has retweeted multiple articles -- from sources like CNN, USA TODAY and Huffington Post -- pointing out the hidden message.
Kammen seems to be following in the footsteps of the president's Arts and Humanities council, which spelled out the word "resist" in its members' collective resignation letter.
Kammen is an energy professor at the University of California at Berkeley.
