Kamala Harris has said her State of the Union guest will be Trisha Pesiri-Dybvik, a California mother of three whose home was destroyed by the Thomas Fire in 2017 and whose family was affected by the recent partial government shutdown.

“Let’s fight for an America where the economy works for working people ― an America where health care and education are fundamental rights, not a privilege for the wealthy few,” she said.

Sen. Kamala Harris (D-Calif.) broadcast a populist message focused around a desire for greater racial and economic justice in the U.S. on Tuesday night, just an hour before President Donald Trump ’s State of the Union address.

“We also need our leaders to speak truth about the threat of climate change, about our broken criminal justice system, about our weakened position in the world and about the realities of racism, sexism, anti-semitism, homophobia and transphobia,” she said.

On what would have been the 24th birthday of Trayvon Martin ― the unarmed Florida teenager who was shot and killed by George Zimmerman in 2012, sparking mass protests and outrage ― Harris spoke of “an America where no mother or father has to teach their son that people may stop him or kill him because of the color of his skin ― and where no parent has to send their child to school with a bulletproof backpack.”

Harris deliberately set herself apart from the president, predicting that Trump would deliver a speech Tuesday night that “seeks to score political points by driving us apart.”

“The strength of our union has never been found in the walls we build,” she said. “It’s in our diversity and our unity, and that is our power.”

“When you hear claims that our problems would all be solved if we just built a wall on our southern border, don’t forget the babies ripped from their parents’ arms and the refugees fleeing violence and abuse who are being turned away,” she said.

The Republican National Committee criticized Harris’ Tuesday comments in a statement sent to HuffPost, describing her as “blinded by her opposition to President Trump.”

″[B]efore he can speak about his bipartisan agenda at the State of the Union, she tried to advance her divisive leftist agenda of government-run health care, higher taxes, and open borders,” RNC spokesman Steve Guest said in a statement.

Former Georgia gubernatorial candidate Stacey Abrams is scheduled to deliver the Democrats’ rebuttal immediately after Trump’s address, followed by Sen. Bernie Sanders (I-Vt.), who will provide his own response to Trump for the third straight year.

Since Harris told ABC’s “Good Morning America” thatshe was running for president last month, she has pulled off themost successful campaign rollout of any Democratic hopeful this cycle, in the eyes of many political operatives. Within 24 hours, sheraised $1.5 million. Over the next week, she appeared on MSNBC’s “The Rachel Maddow Show,” presented her policy views during a CNN town hall, paid a visit to some of her sorority sisters in South Carolina and stood in front of more than 20,000 people at a rally in her hometown of Oakland, California.
