WASHINGTON (AP) — President Donald Trump is governing through the most dangerous practical and political crisis forced upon any U.S. leader in nearly a century. And just seven months before Election Day, he is entering a critical stretch that may determine his reelection, his legacy, and the character of the nation. The coming weeks will test Trump’s leadership under the crushing weight of twin public health and economic crises. Yet it is increasingly the view of Trump and those around him that he is approaching the limits of his power to alter the trajectory of the outbreak and the related economic fallout.
