WATCH: Elizabeth Warren confronted at campaign stop for lying about Native American heritage

Sen. Elizabeth Warren (D-Mass.), who is running for the 2020 Democratic presidential nomination, was reminded once again during a campaign stop in Georgia over the weekend that she lied about having Native American heritage.

What happened?

While speaking at a campaign stop outside Atlanta, a heckler shouted over Warren seeking answers as to why she, for decades, lied about her heritage.

"Why did you lie?" the man shouted.

"Hold on. We'll get to lots of policy, I promise. OK?" Warren responded. "Be easy. Be easy."

According to witnesses, security escorted the heckler out of the Central Gwinnett High School gymnasium as Warren continued on with her speech. The crowd cheered and shouted Warren's name as security handled the man.

Washington Free Beacon editor David Rutz reported that the heckler was holding a "1/2020" sign, a reference to Warren's minuscule Native American heritage.

WATCH:

It's not clear if she ever addressed why she lied about having Native American heritage. However, she told local Atlanta news station WSB-TV afterward that she "shouldn't have done it," referring to lying about her background.

After claiming for years that she was Native American — even going so far as to claim "American Indian" race on her application for the State of Texas Bar — Warren released the results of a DNA test last year showing she is only 1/1024 Native American.

She has since apologized to the Cherokee Nation, the tribe in which she claimed her ancestry was rooted, which had been publicly critical of Warren.
