Chelsea Clinton praised the Roe vs. Wade Supreme Court decision that legalized abortion on Saturday, saying it helped add $3.5 trillion to the U.S. economy.

Clinton was speaking at a pro-abortion rights event "Rise Up For Roe," which was organized in opposition to President Donald Trump's nomination of Judge Brett Kavanaugh to the Supreme Court, CNS News reports.

Clinton said that abortion rights were something that everyone has to care about if they take justice issues seriously.

"Whether you fundamentally care about reproductive rights and access rights, because these are not the same thing, if you care about social justice or economic justice, agency—you have to care about this," Clinton said.

Clinton then tried to connect the controversial 1973 Supreme Court ruling to the American economy.

"It is not a disconnected fact, to address this t-shirt of 1973, that American women entering the labor force from 1970 to 2009 added three and a half trillion dollars to our economy. Right?" Clinton said. "The net, new entrance of women—that is not disconnected from the fact that Roe became the law of the land in January of 1973. So, I think, whatever it is that people say they care about, I think that you can connect to this issue."

Clinton campaigned for her mother, Hillary Clinton, during the 2016 presidential election, and she has been pressed by some progressives to make a political run of her own. She has never held office.

Democrats have warned Kavanaugh's confirmation to the Supreme Court could imperil abortion rights, although Kavanaugh said during his 2006 confirmation hearing for the D.C. Circuit Court that he would follow Roe v. Wade as "binding precedent."
