US Defense Secretary Pete Hegseth vowed in an interview this week that the execution of the man who killed 13 people in a mass shooting at Fort Hood in 2009 would be "public." "We'll make sure that people are able to watch it, that it's public, because people need to understand that there's serious consequences for these types of things," Hegseth told far-right podcaster Jack Posobiec in an interview aboard the USS Abraham Lincoln on Wednesday.
