Making his first comments since Donald Trump won the presidency, Bernie Sanders said the Republican “tapped into the anger of a declining middle class.” But Sanders vowed to “vigorously oppose” Trump if he “pursues racist, sexist, xenophobic, and anti-environment policies. Donald Trump tapped into the anger of a declining middle class that is sick and tired of establishment economics, establishment politics, and the establishment media,” Sanders said, echoing some of the themes of his own campaign. “To the degree that Mr. Trump is serious about pursuing policies that improve the lives of working families in this country, I and other progressives are prepared to work with him. To the degree that he pursues racist, sexist, xenophobic, and anti-environment policies, we will vigorously oppose him,” he concluded.
