In her Saturday speech, Biden honored the submarine’s 136 officers and crew, saying they were “the very best our Navy has to offer.”

During World War II, her father served as a Navy signalman.

The former second lady was among numerous dignitaries who gathered Saturday at the Virginia shipyard that builds aircraft carriers and submarines.

On Friday, Joe Biden met with union leaders and workers at the union hall of Newport News Shipbuilding. The former vice president is among the Democrats who might run for president in 2020.
