The Board of Trustees has come under criticism since November 2018 by groups including Decolonize This Place, the Chinatown Art Brigade, and W.A.G.E., for vice chair Warren B. Kanders' ownership of the company Safariland, which manufactured tear gas used against the late-2018 migrant caravans;[42] 120 scholars and critics published an open letter to the Whitney Museum asking for the removal of Kanders from the museum board; additional signatories after the letter's initial posting included almost 50 artists who have been selected for the 2019 Whitney Biennial.[43] A series of nine weeks of protest by Decolonize This Place highlighted the use of Safariland weapons against protestors and others in Palestine and other places.[44]
