U.S. Sen. Cory Booker is appealing to Americans to come together from their partisan corners as he launches his 2020 presidential candidacy. The New Jersey Democrat appeared live on “The View” on Friday, telling its hosts that he is running as a counterweight to “a caustic type of politics” that threatens to divide the country. Booker, the former mayor of Newark, joins multiple other candidates of color in a diverse Democratic primary field.
