Multiple members of Antifa, a violent protest group that gathered outside the White House on Sunday on the anniversary of the Charlottesville, Virginia, riots, threatened President Donald Trump with physical harm and even murder, it is now being reported.

Sunday’s “Unite the Right 2” white nationalist rally in Washington, D.C., was “a failure,” with only 30 or 40 people showing up to “unite whatever they believe the Right to be,” as The New American reported.

But members of Antifa showed up, too — threatening citizens and law enforcement and causing harm as they descended upon the small crowd.

The Secret Service told the Daily Caller that the agency was “aware” of the threats to the president and was investigating the Antifa protesters, whose hallmark is aggressive and violent behavior — a group the FBI has described as “domestic terrorists.”

Antifa, short for “antifascist,” has been attacking cops, journalists, and peaceful protesters since Trump’s inauguration day in early 2017 — rioting, vandalizing store fronts, and setting cars on fire, among other destructive actions.

“The black-clad stormtroopers, who typically wear masks to hide their identities, are, it appears, bracing for civil war,” noted The New American.

When asked, “If Donald Trump showed up here, what would you say or do?” the answers regularly contained the mention of violent acts.

Protesters looked into the camera and threatened to physically harm or even “murder the president,” noted the Daily Caller.

One member said the group wanted to “do him like Gaddafi,” a reference to actions taken against Libya’s former dictator, Muammar Gaddafi — who was dragged into the street, beaten and murdered by his own people.

Another protester bluntly said he would “murder Trump for the American people.”

During the rally, these individuals chanted anti-American and anti-cop slogans such as “America was never great!” and “All these racists, killer cops, we don’t need them, need them.”

They also chanted at police officers in the area who were there protecting everyone — including them — telling them, “Quit your job.”

In short, angry, violent Antifa members descended on the rally using graphic language and obscene gestures.

And in video taken by Breitbart News, Black Lives Matter activists joined in the fray, attacking cars and threatening drivers who were attempting to drive down the streets of Washington, D.C.

An NPR reporter saw Antifa members “launch fireworks, water bottles, eggs at cops,” while a reporter for USA Today saw them attack a motorcycle cop, noted The New American.
