KNOXVILLE, Iowa (AP) – Democratic presidential candidate Pete Buttigieg is calling former Vice President Joe Biden’s vote to authorize the Iraq War part of the nation’s “worst foreign policy decision” of Buttigieg’s lifetime. The mayor of South Bend, Indiana, was responding to a question about how his foreign policy experience measures up to others’ in the Democratic race, specifically Biden.

Buttigieg says the vote is an example of why years in Washington is not always the same thing as judgment. Buttigieg made the remarks Sunday while taping the program “Iowa Press” on Iowa Public Television.
