Rep. Adam Schiff, the lead investigator in the impeachment inquiry of President Trump, says the House Intelligence Committee's report "shows abundant evidence" that Trump used the power of his office to "condition official acts" in exchange for political favors.

In other words, the California Democrat says Trump met a threshold set forth in Constitution that says a president can be impeached and removed from office for committing treason, bribery or other high crimes and misdemeanors.

"I don't think there's any question that the uncontested facts show this president solicited a bribe," Schiff told NPR's Steve Inskeep in an interview the congressman's office on Capitol Hill Tuesday.

Schiff's comments come as House Democrats have mostly wrapped up the investigation of the president and are moving expeditiously toward a possible impeachment vote that could come ahead of Christmas.

"Bribery ... most importantly in terms of what the founders had in mind, that is conditioning an official act for something of value," Schiff said, adding, "I think this certainly meets that definition."

The interview also as Democrats on the House Intelligence Committee, which Schiff chairs, release a report laying out their case for drafting articles of impeachment. That report also says Trump committed "an unprecedented campaign of obstruction" in the impeachment inquiry. Charges that Schiff calls "very serious."

"It is difficult to imagine a more iron-clad case of obstruction of Congress than this one, where the president instructed all of his departments to refuse lawful subpoenas, not turn over a single document," Schiff says.

He added that if Republicans fail to act, "they must be willing to accept that fact that when there's a Democratic president that they believe is engaged in any presidential misconduct, they will be powerless to find out," because that future president can point to the Trump administration as precedent.

Central to Democrats' argument for impeachment is the allegation that Trump engaged in presidential misconduct when he tried to get Ukraine's President Volodymyr Zelenskiy to open investigations that were politically beneficial to Trump.

Democrats say that in exchange for investigations, which included the family of a political rival former Vice President Joe Biden, the Trump administration would release roughly $400 million in military assistance and grant Zelenskiy an Oval Office meeting with Trump, which officials in Ukraine desperately wanted.

Republicans on the committee argue the Democrats failed to produce any evidence during the impeachment inquiry that proves what Trump did was an impeachable offense.

In their own prebuttal report released Monday, House GOP members accuse Democrats of "trying to impeach a duly elected President based on the accusations and assumptions of unelected bureaucrats who disagreed with President Trump's policy initiatives and processes."

A number of polls, including one from NPR last month, show about half of Americans approve of the impeachment inquiry (50% support compared to 43% who do not). But Americans appear to be split evenly on whether they support Trump being impeached and removed from office — 45% approve to 44% oppose.

Inskeep asked Schiff whether, given that public opinion on impeachment is changing very little and that Trump is unlikely to ultimately be convicted and removed from office by the Republican-controlled Senate, he would be in favor of a less severe outcome than impeachment.

"Would censuring the president – voting to criticize him without trying to remove him from office — be something that would be more in line with public opinion?" Inskeep asked.

Schiff quickly knocked down the idea.

"I'm not a fan of the idea of censure," Schiff says.

"This is a president who is not chastened by the experience of the catastrophe of Russian interference in our last election and is willfully seeking interference in the next election."

The impeachment process now moves to the House Judiciary Committee, which is the panel that will decide whether to draft articles of impeachment that lawmakers would then vote on.

On Wednesday, that panel is scheduled to hear from four legal scholars who will share with lawmakers conditions for impeaching a president. Democrats have called Noah Feldman, a Harvard Law Professor; Michael Gerhardt, a law professor at the University of North Carolina; and Pamela Karlan, who teaches law at Stanford.

Republicans have invited Jonathan Turley, a George Washington University law professor, who has written extensively about the impeachment process, including op-ed columns arguing that Democrats moved too quickly on investigating Trump and the Ukraine controversy.
