Chairman Jerrold Nadler described the 55-page analysis as the heir to the only similar report produced by the Judiciary Committee, which was released during the impeachment proceedings against Richard Nixon. That document was updated during the Bill Clinton impeachment but not fully rewritten.

Democrats view the new, Trump-era document as a touchstone in the nation’s centuries-long struggle to define and apply the most charged tool the Constitution provides to Congress: the power to remove a president. It is also a key step toward an impeachment vote later this year, after the Judiciary Committee began public impeachment hearings last week.

“The earlier reports remain useful points of reference, but no longer reflect the best available learning on questions relating to presidential impeachment,” Nadler writes in the report’s foreword. “Further, they do not address several issues of constitutional law with particular relevance to the ongoing impeachment inquiry respecting President Donald J. Trump.”
