Cory Booker, the junior U.S. senator from New Jersey who previously served as the mayor of Newark from 2006 to 2013, is giving his more than 1.5 million followers on Twitter a crash course on going vegan

Booker, a vegetarian and animal advocate for more than 22 years, started his "vegan experiment" in early November. Two weeks in, he shared that while the transition to animal-free eating wasn't easy, it has already changed the way he views both food and its production.

Booker's experiment has also included some generous plugs for vegan businesses in New Jersey and related causes, such as a petition urging Ben and Jerry's to release a plant-based ice cream. 

While the 45-year-old initially labeled his vegan switch as temporary, it seems there's a good chance he may continue it into the New Year and beyond.
