“Donald Trump has set his ambitions on the White House in order to promote an agenda of fascism and xenophobia as well as the religious persecution of Muslims through totalitarian policies," says the masked speaker in the video.

They say that the time is nigh to unite to “fight fascism” and "to stop any proposed Fourth Reich by the fascist Donald Trump.”

Trump’s campaign issued this statement: "The government and law enforcement authorities are seeking the arrest of the people responsible for attempting to illegally hack Mr. Trump’s accounts and telephone information.”

A government official confirmed to ABC News that federal authorities are investigating.

Anonymous released what it claimed was Trump's Social Security number, and a number it claims is his cell phone number as well as public information such as his birth date, children’s names, and company address in addition to outdated information such as his legal representation.
