Microphones picked up on the group’s shouts as Anderson Cooper attempted to cover the Manhattan attack which killed eight and wounded 12.

The group appears to have been led by Laura Loomer, an outspoken Trump supporter who describes herself as a ‘independent investigative journalist’ online.
Trump has repeatedly branded CNN ‘fake news’ during his press conferences and while holding rallies with his supporters.
While ISIS has not claimed responsibility for the attack, terrorist Sayfullo Saipov is believed to have been carrying propaganda from the terror group in the truck he used to kill eight people and wound 12.
