Hundreds of thousands of women, many with husbands, boyfriends and children in tow, filled the streets of several major US cities on Saturday in an unprecedented wave of mass protests against President Donald Trump the day after his inauguration. Women activists, galvanized by Trump campaign rhetoric and behavior they found to be especially misogynistic, spearheaded scores of US marches and sympathy rallies around the world that organizers said drew nearly 5 million protesters in all.
