President Trump’s evolving positions on China, NATO and other issues can be chalked up to either circumstances moving closer to Trump’s positions or his desire to improve the lives of Americans, White House press secretary Sean Spicer said Thursday.

Trump has been slammed Thursday for flip-flopping on a number of positions. In recent days, he’s deemed NATO no longer “obsolete” as he did on the campaign trail and said China is not a currency manipulator, despite making that a regular part of his stump speech. He’s also praised Federal Reserve Chair Janet Yellen and supported the Export-Import Bank, positions he felt the opposite on during the campaign.
