The casket of former U.S. President George H.W. Bush arrived at the U.S. Capitol on Monday. A 21-gun salute rang out as the flag-draped casket was carried inside. With hands on hearts, dignitaries and family members, including son George W. Bush and wife Laura, stood in mourning. U.S. President Donald Trump and First Lady Melania Trump also paid their respects to George Bush Sr. An invitation-only funeral service is set for Wednesday at Washington National Cathedral.
