President Donald Trump slammed rival Joe Biden’s support for eliminating fossil fuels, a core pledge in the former vice president’s platform for the 2020 election. With Rep. Alexandria Ocasio-Cortez (D-NY) advising his campaign on the “Biden-Sanders Unity Task Force,” Biden embraced a version of the “Green New Deal.” The major difference was that whereas Ocasio-Cortez wants to eliminate fossil fuels in the U.S. economy by 2030, Biden set the deadline at 2035.
