The Human Rights Campaign held its annual national dinner in the nation’s capital on Saturday. Founded in 1980, the group advocates equal rights for lesbian, gay, bisexual and transgender Americans. Headlining the event was Newark, New Jersey Mayor Cory Booker who talked about what he called the “common ancestry” of both the civil rights and gay rights movements. He was introduced by the group’s president - Chad Griffin - who discussed what’s at stake in the November elections for those fighting for gay rights and marriage equality.
