During the 2000s, many North American local governments, school systems, transit agencies, and even airlines passed laws and regulations against the practice of wearing sagging pants, although no state or federal laws have been enacted banning the practice. US presidential candidate Barack Obama, speaking just before the 2008 US Presidential Election, appeared on MTV and said that laws banning the practice of wearing low-slung pants that expose one's underwear were "a waste of time ... Having said that, brothers should pull up their pants. You are walking by your mother, your grandmother, your underwear is showing. What's wrong with that? Come on. Some people might not want to see your underwear. I'm one of them."
