(CNN) House Judiciary Chairman Jerry Nadler said Monday he believes the House should impeach President Donald Trump, and now it's his committee's job to convince the public that it's the correct course of action before the House moves forward.

"Personally, I think the President ought to be impeached," Nadler told WNYC's Brian Lehrer.

Nadler's comments were some of the most detailed he has offered thus far about his rationale for the House to pursue impeachment. He said that he believes the House should act on impeachment, even if the Senate will not remove the President, because Congress has to "vindicate the Constitution."

"We have to show that this kind of behavior -- trashing the Constitution, trashing all the norms which guarantee democratic government, aggrandizing power to the Presidency and destroying the separation of powers and thereby leading the President to become more and more of a tyrant cannot be tolerated. And it cannot be normalized," Nadler said. "We have to make sure the next President or the one after him or her knows there's a real penalty to be paid. That's why the impeachment is necessary, even if we cannot get a vote in the Senate."

The New York Democrat cited multiple allegations his committee is investigating, including Trump's alleged violations of the Emoluments clause of the Constitution, public corruption, obstruction of justice and abuse of power, as well as defying congressional subpoenas.
