STAND WITH US Dear Larry - It's on: ExxonMobil CEO Rex Tillerson, whose dubious credits include close ties to Vladimir Putin, sanction-defying business deals with Iran, and millions in donations to climate-change denial groups, is, after yesterday's Senate confirmation hearing, one step closer to becoming Secretary of State. Tillerson's countless conflicts of interest and relationships with dictators and oligarchs make him the most dangerous cabinet pick in recent memory. His record at ExxonMobil -- corruption schemes, human rights abuses, investor fraud -- paints a terrifying picture of America's diplomatic future.
