(CNN) The US ambassador to the United Nations, Nikki Haley, has told CNN that removing Syrian President Bashar al-Assad from power is a priority, cementing an extraordinary U-turn in the Trump administration's stance on the embattled leader. Two days after the US launched military strikes on a Syrian airbase in response to a chemical weapons attack widely blamed on the Assad regime, Haley said Assad's departure was inevitable. But before Tuesday's chemical attack on the rebel-held town of Khan Sheikhoun, which killed 89 people, Haley had said toppling Assad was not a priority. President Donald Trump, before his election, described fighting ISIS and seeking Assad's removal at the same time as "idiocy."Haley says Assad hinders political solution for SyriaShe warns US could carry out more strikes on regime
