According to the NY Post:
“A topless protester disrupted Sen. Bernie Sanders’ campaign rally in Nevada on Sunday — moments after Mayor Bill de Blasio introduced the Democratic presidential candidate to the stage.
...
Sanders moved to the edge of the stage as a string of women then paraded across holding images of cows — followed by a topless woman, who gestured to Sanders as members of his security detail positioned themselves between the two.“
