WASHINGTON -- A "solemn day" or a "show trial"?
Americans and the world can decide for themselves as House Democrats let the public in to the impeachment proceedings against President Donald Trump.
House Intelligence Committee Chairman Adam Schiff opened the first hearings Wednesday into Trump's pressure on Ukraine to investigate Democratic rival Joe Biden's family.
"Must we simply `get over it?"' Schiff asked in the hearing's first moments.
Other big questions loom, including how strongly officials connected what Trump called that "favour" to U.S. military aid for Ukraine. Impeachable offences? Worthy of Trump's removal? And, critically, will a parade of diplomats and their accounts nudge more Americans behind formally charging Trump in the shadow of the 2020 elections?
Here's what to know about the first hearing, with the charge d'affaires in Ukraine, William Taylor, and a career diplomat, George Kent, at the witness table:
------
FIRST, KNOW THIS
"The President, Vice-President and all civil officers of the United States, shall be removed from office on impeachment for, and conviction of, treason, bribery, or other high crimes and misdemeanours."
Expect numerous mentions of Article 2, Section 4 of the Constitution, especially on whether Trump's own words and actions meet the vague threshold of "high crimes and misdemeanours." Some Democrats and diplomats say conditioning U.S. aid on whether Ukraine goes after Biden's son Hunter sounds like "bribery." Republicans deny that, saying Trump did not explicitly offer aid for the Biden probe.
What it's not: a trial, which would be conducted by the Senate if the House approves articles of impeachment. So no matter what the president tweets, he is not entitled to a defence attorney. The proceedings are the due process he says he's being denied, though they are controlled by Democrats in ways Republicans will say is unfair.

... AND THIS
It's only the fourth time in American history that Congress has launched impeachment proceedings against a sitting president. Two of those -- against Andrew Johnson in 1868 and Bill Clinton 130 years later -- resulted in their impeachments, or formal charges approved by the House. Both were acquitted by the Senate.
President Richard Nixon resigned in 1974 before the House could vote to impeach him.

THE SPIN
With only hours to go before the hearing, Republicans and Democrats from Congress to the campaign trail were spinning their points of view.
"Well, it's a calm day, it's a prayerful day, it's a solemn day for our country," House Speaker Nancy Pelosi said Tuesday night on the eve of the hearings. "It's a sad day, which I wish we never had to face."
"A phoney show trial," Trump groused a few hours later.
Trump also has called the process a "total impeachment scam." He's offering his own counterprogramming with a White House visit from Turkish President Recep Tayyip Erdogan, which is its own story of war, trade and tension.

THE SPARK
A whistleblower's complaint about Trump's July 25 telephone call with Ukrainian President Volodymyr Zelenskiy ignited the impeachment investigation. Trump responded on Sept. 24 by releasing a rough transcript.
During the hearing Wednesday, listen for discussion about a key exchange during that 30-minute call, in which Zelenskiy invokes the still-blocked military aid and the U.S. president responds: "I would like you to do us a favour though." Trump then asks Zelenskiy to investigate a debunked conspiracy theory about the 2016 election and later explicitly mentions the Bidens.
Trump says the call was "perfect" and contained no "quid pro quo," or this for that.
Democrats say it shows Trump using his office to pressure a foreign government to help him politically.

'INVESTIGATIONS, BIDEN and CLINTON'
Democrats chose Taylor and Kent to start the storytelling of public hearings. They will describe a parallel foreign policy toward Ukraine led by Trump's personal attorney Rudy Giuliani and other White House officials.
"I discovered a weird combination of encouraging, confusing and ultimately alarming circumstances," Taylor testified in an Oct. 22 statement. He is a West Point graduate and Vietnam War veteran who has served under every presidential administration, Republican and Democrat, since 1985, and worked for then-Sen. Bill Bradley, D-N.J.
Kent, the bow tie-wearing career foreign service officer, testified on Oct. 15 that there were three words Trump wanted to hear from the Ukraine president: "Investigations, Biden and Clinton."
He also told the investigators about the "campaign of lies" against former U.S. ambassador to Ukraine Marie Yovanovitch that he said was waged by Giuliani and contributed to her being recalled from the position.

THE RINGER
Republicans have added House Rep. Jim Jordan to the Intelligence Committee. Although Nunes is the senior Republican, look for the congressman from Ohio to act as an especially fierce attacker of the witnesses' credibility and the Democrats' case for impeachment.
At its heart, the GOP argument is that the impeachment effort is unfair and sparked because "unelected and anonymous bureaucrats disagreed" with Trump's decisions on Ukraine.
Some Republicans have urged the outing of the whistleblower.
U.S. whistleblower laws exist to protect the identity and careers of people who bring forward accusations of wrongdoing by government officials. Lawmakers in both parties have historically backed those protections.
The Associated Press typically does not reveal the identity of whistleblowers.

WHAT AMERICANS THINK NOW
An AP-NORC Center poll conducted in late October found Americans more approving than disapproving of the impeachment inquiry, 47% to 38%.
Even in the throes of impeachment, approval of the president's job performance has not changed significantly.

NEXT UP
Yovanovitch, a two-time ambassador, testifies Friday as the next in the series of hearings expected to stretch through next week.
