WASHINGTON ― A left-wing political group released a new video Monday of a counter-sting that has uncovered evidence of right-wing activists trying to sow chaos at Donald Trump’s inaugural ceremony, an effort to portray critics of Trump who march against him as violent fringe figures.
The counter-sting, carried out by The Undercurrent and Americans Take Action, a project of a previous target of provocateur James O’Keefe, managed to surreptitiously record elements of O’Keefe’s network offering huge sums of money to progressive activists if they would disrupt the ceremony and “put a stop to the inauguration” and the related proceedings to such a degree that donors to the clandestine effort would “turn on a TV and maybe not even see Trump.” To have riots blot out coverage of Trump, the donor offered “unlimited resources,” including to shut down bridges into D.C.
The Undercurrent, led by executive producer Lauren Windsor, is sponsored by American Family Voices, which was among a constellation of groups infiltrated by O’Keefe’s Project Veritas during the presidential campaign, an effort to link Democrats with voter fraud.
