Q: What became of Campbell Brown, who left NBC for CNN and then left that network?

— S. Lloyd Martin, Decatur

A: Brown, a former reporter and anchor for NBC and CNN, is the co-founder of New York's The Parents' Transparency Project, "a watchdog group whose mission is to bring transparency to the rules, deals and contracts negotiated between our state and local governments and the teachers' unions," according to its website (ParentsTransparency.org). Brown also is on the organization's board of directors. Brown, 45, has two children and lives in Manhattan. Brown, who has a website (CampbellBrown.com) and is active on Twitter (@campbell_brown), left CNN in 2010, stating at the time: "The simple fact is that not enough people want to watch my program, and I owe it to myself and to CNN to get out of the way so that CNN can try something else." She also said she wanted to spend more time with her children.

Q: Does the U.S. Postal Service have tracking devices on its vehicles like UPS and FedEx? If not, why?

— Al Cooper, Atlanta

A: There are no tracking devices on USPS vehicles, spokesman Michael Miles told Q&A on the News in an email. "The Postal Service has more vehicles than both UPS and FedEx combined, so equipping each of them with tracking devices would not be practical," Miles wrote. "Also, unlike its competitors, many postal deliveries are made on foot."
