Politico says a reporter has resigned after editors determined she had plagiarized stories about transportation, most recently from a New York Times article.
Editor-in-chief John F. Harris and executive editor Jim VandeHei said in an online note that the stories by Kendra Marr "borrowed from the work of others, without attribution, in ways which we cannot defend and will not tolerate."
VandeHei confirmed the information on Thursday night.
A voicemail left at a cellphone number for Marr wasn't immediately returned.
Politico says a senior editor received an email from a Times writer Wednesday pointing out similarities in stories in the two publications. Editors say on Thursday when they compared the articles and six other pieces by Marr, they found "troubling similarities to work earlier published by others."
Politico is based in Arlington, Va.
