U.S. Supreme Court Justice Samuel Alito unexpectedly recused himself from a major climate change case scheduled for next week, involving ExxonMobil and Suncor Energy. Environmental groups had previously called for Alito to recuse himself, citing his ownership of oil company stocks. Alito's recusal could lead to a 4-4 tie in the Supreme Court's decision on the case, which would uphold the lower court's ruling allowing the lawsuit to proceed.
