Fighting for the rights of immigrants and the impoverished during the Great Depression, Fiorello La Guardia was considered "America's mayor" by millions of New Yorkers during his 12 years in office. In a new book about La Guardia, journalist and historian Terry Golway looks at the many political lessons to be learned from the former mayor's leadership — and how they can be applied today.

Golway joined NY1's Errol Louis to talk about La Guardia's legacy and discussed his post-mayoral life, the funny story of how an airport opened in his name and how La Guardia would be perceived in today's political climate.
