Raymond C. Offenheiser, president of Oxfam America

Raymond C. Offenheiser, president of Oxfam America, an antipoverty organization, said his group questioned how Mr. Tillerson would “balance the pressure to transact short-term deals against his larger responsibility to strengthen the rules and institutions that protect economic hope and fundamental human rights for so many on the planet.”

Mr. Offenheiser added, “Under Tillerson’s leadership, Exxon has continued to work to undermine climate science.”
