'We march for moral core, against which Trump is waging war,' says America Ferrera

Thousands of women and men, including numerous Hollywood celebrities, took to streets in Washington D.C., just a day after Donald Trump was inaugurated as the 45th president of the United States.

Latina activist and actress America Ferrera told the Washington crowd: "It's been a heart-wrenching time to be a woman and an immigrant in this country ? a platform of hate and division assumed power yesterday."

"We march today for the moral core of this nation, against which our new president is waging a war."

"Our dignity, our character, our rights have all been under attack and a platform of hate and division assumed power yesterday. But the president is not America. ... We are America and we are here to stay," she said, as reported by The Hollywood Reporter.

Ferrera was the first of a host of keynote speakers at the march, including Gloria Steinem, Scarlett Johansson, LGBTQ activist Janet Mock, Michael Moore and civil rights activist Angela Davis.

Scarlett Johansson addressed President Donald Trump directly from the podium, saying, "I didn't vote for you but I respect the fact that you are the president. But before I support you, I ask you to support me."

She asked him to ensure that her daughter gets to grow up with the same ones his daughters enjoy.

The Women's March on Washington is a grassroots response to Trump's unexpected electoral victory over Hillary Clinton, who was the first major party female candidate in US history.
