US Constitutional Scholars Testify at Trump Impeachment Hearing Ken Bredemeier WASHINGTON - The next step by congressional Democrats pushing the impeachment of U.S. President Donald Trump is unfolding Wednesday, with four constitutional scholars testifying on what they believe the country's founding fathers intended when they decided how a president could be impeached and removed from office. The Democratic majority on the House Judiciary Committee is calling law professors Noah Feldman of Harvard, Pamela Karlan of Stanford and Michael Gerhardt of North Carolina to advance their case that Trump abused the presidency by pushing Ukrainian President Volodymyr Zelenskiy to investigate one of his chief 2020 Democratic rivals, former Vice President Joe Biden, his son Hunter's work for a Ukrainian natural gas company and a debunked theory that Ukraine, and not Russia, meddled in the 2016 U.S. election. Watch Hearing LIVE: In a prepared opening statement, Gerhardt says, "If Congress fails to impeach here, then the impeachment process has lost all meaning, and, along with that, our Constitution's carefully crafted safeguards against the establishment of a king on American soil. No one, not even the president, is beyond the reach of our Constitution and our laws." Republicans defending Trump are calling George Washington University law professor Jonathan Turley to buttress their contention that Trump did nothing wrong while asking for the Ukrainian investigations at the same time he was withholding $391 billion in military aid Kyiv wanted to help fight pro-Russian separatists in eastern Ukraine. Trump eventually released the assistance in September without Ukraine opening the Biden investigations, proof, Republicans say, that there was no quid pro quo, an exchange of favors between Trump and Ukraine. .
