Pelosi said in a statement that her family is "devastated" by the loss of her "beloved brother."

“Tommy was the finest public servant I have ever known," Pelosi said in the statement. "His life and leadership were a tribute to the Catholic values with which we were raised: faith, family, patriotism. He profoundly believed, as did our parents, that public service was a noble calling and that we all had a responsibility to help others."

Pelosi commended her brother for dedicating "his life to our city."

“All his life, Tommy worked on the side of the angels," the Speaker's statement said. "Now, he is with them. With his commitment to his family and public service, his life has truly blessed America."

D'Alesandro, Pelosi's oldest brother, served as mayor during a turbulent period for the city that saw the 1968 riots and strikes by city workers, bus drivers and symphony musicians, according to the Sun. The mayor took office promising to "root out every cause or vestige of discrimination."
