I love our country &amp; company. I am stepping down from the council to focus on inspiring &amp; uniting through power of sport. - CEO Kevin Plank pic.twitter.com/8YvndJMjj1&mdash; Under Armour (@UnderArmour) August 15, 2017 Kevin Plank, chief executive of athletic equipment maker&nbsp;Under Armour Inc., announced in a tweet Monday that he was stepping down from a White House manufacturing council&nbsp;&ldquo;to focus on inspiring &amp; uniting through power of sport.&rdquo;He indicated that controversy over the&nbsp;criticism&nbsp;President Trump&nbsp;received for not explicitly condemning white supremacists after violent clashes with counter-protestors turned deadly in Charlottesville, Va., on Saturday&nbsp;led to his decision, saying the company &ldquo;engages in innovation and sports, not politics.&rdquo;Plank became the second CEO to step down from Trump's manufacturing council. Kevin Frazier, chief executive of pharmaceutical giant Merck &amp; Co.,&nbsp;publicly resigned from the council Monday morning, declaring he felt &ldquo;a responsibility to take a stand against intolerance and extremism."Soon after, Trump lashed out at Frazier on Twitter.
