As women and allies march across the country in the Women’s March, Sen. Elizabeth Warren participated in the events in Boston — with her own fiery speech criticizing President Donald Trump.

“We’re here today because of the power of women,” Warren said. “The power of women to come up with good ideas, like this rally. The power of women to organize, like this rally. And the power of women to make sure that as our country enters a new political era that the voices of the people will be heard.”

She added, “Yesterday, Donald Trump was sworn in as president. That sight is now burned into my eyes forever. And I hope the same is true for you — because we will not forget. We do not want to forget. We will use that vision to make sure that we fight harder, we fight tougher, and we fight more passionately than ever — not just for the people whom Donald Trump supports, but for all of America.”
