Tobacco claimed another victim Wednesday — President Donald Trump's pick to head of the Centers for Disease Control and Prevention. Dr. Brenda Fitzgerald tendered her resignation following a Politico report that she “bought shares in a tobacco company one month into the leadership of the agency.” There was no additional comment from Fitzgerald, who is a doctor and the former Georgia Department of Public Health commissioner. Fitzgerald also declined to explain to Politico why she purchased thousands of dollars of Big Tobacco stocks after assuming leadership of the CDC on July 7.
