Federal Reserve Chairman Jerome Powell said in a speech before the graduation ceremony at Princeton University on Sunday that becoming an honest public servant is always a worthwhile choice. At this point, he has faced relentless personal attacks from President Trump for several months. Powell stated, 'As you move forward in a world full of bright opportunities, I urge you to embrace challenges and seize the chance to serve your fellow citizens. Fifty years from now, you will want to look in the mirror and know that you did what you believed was right at every stage of your life.' He said, 'Ultimately, integrity is all you have. Please guard it carefully.'
