Former U.S. Attorney General Loretta Lynch on Thursday publicly welcomed what she termed the “rising tide of impeachment,” saying the House’s investigation of President Donald Trump’s dealings with Ukraine was “brought about, as all good reckonings are, by the actions of the president himself.”

Speaking at a conference in Washington, Lynch said the House’s impeachment inquiry carried echoes of the process involving President Richard Nixon more than four decades ago. Her remarks came as Trump’s ambassador to the European Union, Gordon Sondland, appeared on Capitol Hill and testified that he objected to the president’s request to run Ukraine policy through his personal lawyer Rudy Giuliani.
