Sen. Barbara Boxer (D-CA) says GOP frontrunner Donald Trump doesn’t deserve “even one woman’s vote” after he targeted rival Sen. Ted Cruz’s (R-TX) wife, Heidi.

Boxer’s post on Twitter comes after Trump went after Cruz for a Super PAC ad shaming Melania Trump for a partially nude photo she took in 2000 for a G.Q. photo shoot. Trump threatened to “spill the beans” about Heidi.

Boxer, who is retiring this year, supports Hillary Clinton for president.
