The weekend has brought further protesting and demonstrations throughout the country from Washington, D.C. to Southern California, with famous faces continuing to pop up in the crowds of protesters.Two of those seen on Saturday were rocker Pink and her husband Carey Hart, who each posted to their Instagram accounts from a protest in what looked to be a sunny square somewhere in theSanta Ynez Valley where they reside.The Grammy-winning musician, 40, posed in a blue T-shirt that displayed the word 'Nah.' over the subheading, 'Rosa Parks, 1955'.
