KEY POINTS
  • Rep. Jerry Nadler, D-N.Y., sat down with CNBC’s John Harwood to discuss the challenges he and his fellow House Democrats face in their oversight of President Trump and his administration.
  • Nadler first took on the future president as a New York assemblyman in the 1980s when he joined the resistance to a massive Trump development project on Manhattan's Upper West Side.
  • Trump won that battle, though his development got downsized. In today's confrontation over potential impeachment, the entire country holds a stake.

After a quarter-century in Congress, Rep. Jerry Nadler of New York stands on the brink of an outsize role in American political life.

As Judiciary Committee chairman in the Democratic-controlled House, Nadler leads his party's efforts to exercise oversight of President Donald Trump and his administration. If Democrats pursue the fourth serious presidential impeachment effort in American history, Nadler would wield the gavel when it starts.
