Democratic 2020 U.S. presidential candidate and U.S. Senator Elizabeth Warren (D-MA) speaks at a campaign Get Out the Vote Event in Charleston, South Carolina, February 26, 2020.

Sen. Elizabeth Warren, D-Mass., unveiled a bill Thursday to divert money from President Donald Trump's border wall to the U.S. coronavirus response.

As concerns rise about the outbreak spreading in the U.S., the 2020 Democratic presidential candidate argued the $1.25 billion in emergency funding sought by the president is inadequate. With the proposal, Warren not only aims to confront a budding public health crisis but also looks to knock a Trump policy she has called racist and divisive.

"The coronavirus outbreak poses serious health, diplomatic, and economic threats to the United States, and we must be prepared to confront it head-on," Warren said in a statement. "Rather than use taxpayer dollars to pay for a monument to hate and division, my bill will help ensure that the federal government has the resources it needs to adequately respond to this emergency."

Warren is among the Democratic presidential candidates who have focused more on the coronavirus this week. On Wednesday, the Centers for Disease Control and Prevention confirmed the first potential community transmission of the virus in the U.S. — a person who did not have the travel history or contact with a patient that would have put them at risk.

Top presidential candidates — Sen. Bernie Sanders, I-Vt., former Vice President Joe Biden, former New York Mayor Mike Bloomberg, former South Bend, Indiana, Mayor Pete Buttigieg, Sen. Amy Klobuchar, D-Minn., and Warren — have criticized the Trump administration's response to the coronavirus. Warren and Bloomberg have already put out out plans to improve responses to public health crises.
