Massachusetts Senator Elizabeth Warren vowed that the Democratic Party would "stand up to bigotry" in the wake of the election of Donald Trump and said the president-elect "encouraged a toxic stew of hatred and fear” during the 2016 presidential campaign.

"We will stand up to bigotry. No compromises ever on this one. Bigotry in all its forms," Warren said in a speech Thursday to the AFLO-CIO labor federation. “We will fight back against attacks on Latinos, on African Americans, on women’s, on Muslims, on immigrants, on disabled Americans, on anyone.”

“Whether Donald Trump sits in a glass tower or sits in the White House, we will not give an inch on this, not now, not ever,” Warren added. The Democratic firebrand was vocal in her criticism of Trump during the presidential campaign, engaging in several Twitter battles with the then-Republican nominee and campaigning across key battleground states for Democratic nominee Hillary Clinton.

Later Thursday, in an exclusive interview with MSNBC's Rachel Maddow, Warren said "this is painful, this really and truly hurts and we have to remember how Donald Trump started this campaign ... his entire campaign was fueled on racism and bigotry."

“He won — and now Latinos and Muslim-American children are worried about what will happen to their families,” she said in the earlier speech. "LGBT couples are worried that their marriages could be dissolved by a Trump-Pence Supreme Court. Women are worried that their access to desperately needed health services will disappear.”

Warren said that while many Americans have a right to be worried about a Trump presidency as president-elect, Trump “has an opportunity to chart a different course: to govern for all Americans and to respect our institutions.”

Citing Trump’s victory speech early Wednesday, Warren said Trump then “pledged that he would be 'president for all' "of the American people.

“And when he takes the oath of office as the leader of our democracy and the leader of all Americans, I sincerely hope that he will fulfill that pledge with respect and concern for every single human being in this country,” she said. “No matter who they are, no matter where they come from, no matter what they believe, no matter whom they love.”

Her sentiments were similar to one she gave in a statement to the Boston Globe on Wednesday, saying "President-elect Trump promised to rebuild our economy for working people" and offered to put her differences aside to work with him on that task.

But the senator warned Thursday that if Trump and the GOP “try to turn loose the big banks and financial institutions so they can once again gamble with our economy and bring it all crashing down, then we will fight them every step of the way. Every step.”

She told Maddow, "We are not turning this country over to what Donald Trump has sold, we are just not."

Warren again called on Trump to stick to his promise to be president "for all" Americans, and said she would "put aside" her differences with him to work on issues of economic security and reigning in Wall Street.

Warren also said she had spoken to Hilary Clinton since her defeat on Election Day.

"She has had 25 years of public service," Warren told Maddow. "That has been the defining feature of her life and this [losing] is hard."
