“My deep emotional connection to my mother, a remarkable woman who made a hard choice to save her children, and who valiantly struggled to care for us as a single parent, is the current that has driven my entire life,” Hirono said.

“Now, because she can no longer bear witness for herself, I am choosing to bear witness on her behalf by telling the story of the daughter she inspired to live boldly and to fight for the promises of this country,” the senator added.

Hirono’s mother fled an abusive marriage in Japan, the AP noted.
