On Friday, House Republicans launched their "Commitment to America" agenda. NBC senior congressional reporter Scott Wong and Politico national political reporter Holly Otterbein join us to speak about the agenda and latest on Senate and Governor races in Pennsylvania. Then, it's banned books week, and residents across U.S. communities weigh in on what it means to see books being pulled from shelves in schools and public libraries. Jonathan Friedman, director of free expression and education programs at PEN America, joins us. And, a new study shows that there are 20 quadrillion ants on Earth, and that's a conservative estimate. Entomologist Adam Hart joins us to talk about the study and what all those ants mean.
