This week, our nation marks the 50th anniversary of Rev. Martin Luther King Jr.'s assassination. Last month, we joined colleagues from both sides of the aisle on the Faith and Politics Institute's annual Civil Rights pilgrimage to pay tribute to King and remember his legacy. Visiting Selma, Montgomery and Memphis on a journey led by our colleague, Civil Rights hero Rep. John Lewis of Georgia, reinvigorated our determination to fight for civil rights and equality in Congress. Standing in Memphis at the site of King's murder imbued us with a sense of responsibility to carry on the work he led.
