President Richard Nixon’s daughter Tricia and Grace Slick are both alumnae of Finch College, and Slick was invited to a tea party for the alumnae at the White House in 1969. She invited anarchist Abbie Hoffman to be her escort and planned to spike President Nixon’s tea with 600 micrograms of LSD (an enormous amount), but the party had been billed as an “all ladies” event. Hoffman’s presence in the waiting line immediately aroused the suspicions of White House security personnel; he claimed to be Slick’s “bodyguard and escort,” which failed to convince the security personnel, who told him that the event was “strictly for females.” Hoffman then took out a black flag with a multicolored marijuana leaf and hung it on the White House gate. Slick declined to attend once Hoffman was denied entry, and the two ran across the street to a waiting car. Slick later speculated that she only received the invitation because it was addressed to “Grace Wing” (her maiden name), and that she never would have been invited if the Nixons had known that she was Grace Slick.
