Mr. Dimitri Simes will retire as president of the Center for the National Interest (CFTNI) and publisher of The National Interest on Dec. 31, according to Politico.
The think tank hosted Donald Trump's first major foreign policy address, leading to one of CFTNI's scholars being fired for criticizing the decision in an op-ed article.
The Trump campaign's interactions with Mr. Simes and CFTNI became part of the 2017-2019 Special Counsel investigation.
The Mueller report ultimately found to evidence of wrongdoing by Simes or CFTNI, but the investigation reportedly hurt the think tank financially.
The think tank was established by former president Richard Nixon in 1994, as the Nixon Center for Peace and Freedom. The group changed its name to the Nixon Center in 1998. It was renamed Center for the National Interest in 2011.
Simes annual salary is around $400,000 per year. No successor has yet been named.
