On December 4, 2019, Feldman—alongside law professors Pamela Karlan, Michael Gerhardt, and Jonathan Turley—testified before the House Judiciary Committee regarding the constitutional grounds for presidential impeachment in the impeachment inquiry against President Donald Trump. "Some day, we will no longer be alive, and we will go wherever it is we go, the good place or the other place, and we may meet there Madison and Hamilton," Feldman suggested. "And they will ask us, 'When the president of the United States acted to corrupt the structure of the republic, what did you do?' And our answer to that question must be that we followed the guidance of the framers, and it must be that if the evidence supports that conclusion, that the House of Representatives moves to impeach him."
