Washington (CNN) Sen. Elizabeth Warren said Wednesday that President Donald Trump is a white supremacist, making her rebuke of the President one of the strongest from the crowded field of Democratic presidential candidates candidates in the wake of two mass shootings in the US, one involving a white supremacist suspect.

Warren, who answered "yes" when asked by the The New York Times during a campaign stop in Iowa if Trump is a white supremacist, told the paper that Trump "has given aid and comfort to white supremacists" and "done the wink and a nod. He has talked about white supremacists as fine people. He's done everything he can to stir up racial conflict and hatred in this country."

The comments from the Massachusetts Democrat come several days after she told CNN's Don Lemon on "CNN Tonight" that Trump should not "wink and nod and smile" about white supremacy in the wake of two mass shootings in the US in the span of 13 hours. One of the shootings involved a white supremacist suspect who is believed to have authored a racist, anti-immigrant document targeting Hispanics.

The remarks make Warren the second 2020 Democrat to say the President is a white supremacist following the attacks and a series of racist comments recently made by Trump that included his calls for four minority congresswomen to "go back" to the countries from which they came (three of the four lawmakers are natural-born US citizens). On Monday, New York Sen. Kirsten Gillibrand, who is also seeking her party's nomination for the presidency, told CNN's John Berman on "New Day" that Trump "is not only egging on white supremacy and white nationalism, but he is one himself."

During her interview on Sunday, Warren told Lemon that, "White supremacy is a domestic terrorism threat in the same way that foreign terrorism threatens our people," adding, "it is the responsibility of the President of the United States to help fight back against that. Not to wink and nod and smile at it and let it get stronger in this country."
