The athletic wear and gear brand took some heat in social media circles and from one of its key brand ambassadors, Stephen Curry of the Golden State Warriors, after a CNBC interview with CEO Kevin Plank during which he praised Donald Trump for being pro-business. Mr. Plank was critical, however, of Mr. Trump’s support for a border adjustable tax, which would raise the price of imports into the U.S. Following the interview, Under Armour said its actions were non-political and that it supports an “inclusive immigration policy” and tax reform.
