Gertz has been a media fellow at the
Hoover Institution on War, Revolution and Peace at
Stanford University. In 2008, Gertz was subpoenaed to the
Santa Ana, California federal court to testify in the case of
Chi Mak, who was convicted of providing
United States Navy technology to
China. Gertz refused to answer questions about his sources, citing the
Fifth Amendment. Gertz was a senior editor at the
Washington Free Beacon until October 2019, when he was fired upon the discovery of "a previously undisclosed financial transaction." Gertz had taken a US$100,000 loan from
Guo Wengui, whom Gertz called a "leading Chinese dissident" in his reports. Gertz later rejoined
The Washington Times full time. ==Writings==
