Pete Yost was an investigative reporter for The Associated Press with a fierce, determined style of interviewing that contrasted with his low-key, modest personality. He covered many of the biggest stories of his time and was known throughout Washington journalism and political circles as a dogged investigator who didn’t put up with spin and shading the truth. He got his first taste of journalism as a teenager working at The Philadelphia Inquirer. He graduated from the University of Missouri in 1969, then worked at the Jackson Citizen Patriot in Michigan and The Flint Journal, where he met his wife, Ann, a journalist and novelist. Yost started in the AP Detroit bureau in 1972, moving to the Washington, D.C., bureau in 1983, covering legal affairs and other beats until retiring in January 2015 because of the onset of Lewy body dementia. He passed on Oct. 20, 2020, at 73.
