Thomas D’Alesandro III, the brother of Speaker of the House Nancy Pelosi (D-Calif.) and former Baltimore mayor, died Sunday, Oct. 20 at age 90 due to complications from a stroke.

“My husband Paul and our entire family are devastated by the loss of our patriarch, my beloved brother, Thomas D’Alesandro III,” Pelosi said Sunday. “Tommy was the finest public servant I have ever known.”

Pelosi continued, “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.”

D’Alesandro died at his Baltimore home after experiencing complications from a stroke, according to The Baltimore Sun

He served as mayor for the city during a tumultuous time that, according to the Sun, saw the 1968 protests and strikes by construction workers, bus drivers and symphony musicians. The mayor took office pledging to “root out every cause or vestige of discrimination.”

Pelosi is visiting in Syria

His death comes as Pelosi is visiting Jordan to meet with officials on the crisis unfolding in Syria.

She led a group of American lawmakers on a surprise visit to Jordan to discuss “the deepening crisis” in Syria amid a U.S.-brokered cease-fire.

Pelosi, along with the nine-member congressional delegation, met with Jordan’s King Abdullah II in the capital of Amman late Saturday for talks focusing on security and “regional stability,” according to a statement from her office.

The delegation included Democrats Adam Schiff, chairman of the Intelligence Committee, who is leading the impeachment probe into President Trump; Eliot Engel, chairman of the Foreign Affairs Committee and Bennie Thompson, chairman of the Homeland Security Committee. There was one GOP member in the group, Rep. Mac Thornberry, the top Republican on the House Armed Services Committee.
