WASHINGTON - Democrats told President Donald Trump's impeachment trial Thursday that he openly and dangerously abused his powers to gain political advantage.
House impeachment managers laid out the evidence for the first of two articles of impeachment against the US leader in the second day of arguments, methodically dismantling Republican claims that Trump did nothing wrong in soliciting electoral help from Ukraine last year.
As the 100 senators sat as jurors, the prosecutors played old videos in which two of the president's closest defenders said that abuse of power is a clear impeachable offense, puncturing a key White House argument that the US constitution requires a specific crime to remove a president.
"President Trump used the powers of his office to solicit a foreign nation to interfere in our elections for his own personal benefit," House Judiciary Committee Chair Jerry Nadler, one of the impeachment managers, told the chamber.
"Since President George Washington took office in 1789, no president has abused his power in this way," Nadler said.
"The president has repeatedly, flagrantly, violated his oath... The president's conduct is wrong. It is illegal. And it is dangerous."
'LOADED WITH LIES'
Democrats were planning to spend Thursday's trial session arguing their case on the first impeachment charge, and take on the second -- obstruction of Congress -- on Friday.
That will be the prosecution's final day before Trump's defense takes the Senate podium from Saturday to Tuesday.
Democrats are hoping to break Republican unity and vote with them to remove the president -- an uphill battle given the Republicans' 53-47 majority in the Senate and Trump's ability to keep his party in line.
They are also hoping that, ten months before national elections, the nationally televised hearings will sway voters dubious of impeachment that Trump is unworthy of reelection.
After reports that many republicans were absent from much of Wednesday's session, House Chaplain Barry Black opened the hearing Thursday with a invocation call to listen.
"Lord, help them remember that listening is often more than hearing," he said. "It can be an empathetic attentiveness that builds bridges and unity."
At the White House, Trump unleashed a barrage of tweets attacking the process as "loaded with lies and misrepresentations."
He attacked Adam Schiff, the chief House prosecutor who led the opening arguments Tuesday, in starkly personal terms, calling him "Shifty Schiff," and retweeted criticism of the California lawmaker made by White House supporters to Fox News.
HIGH CRIMES AND MISDEMEANORS
Nadler, a longtime adversary of the New York real estate tycoon, challenged a key tenet of the president's legal defense: that neither of the charges against him, abuse of power and obstruction of Congress, constituted a criminal charge matching the US Constitution's stipulation for "high crimes and misdemeanors" for impeachment.
He reached deep into English law for the origins of the phrase, as defining "offenses against the nation itself."
And he cited the writings of the men who authored the US constitution in the 1780s, the "framers" much hallowed in US history.
"The framers were not naive. They knew that power corrupts," Nadler said.
"Simply stated, impeachment is the constitution's final answer to a president who mistakes himself for a king."
Underscoring the point, he taunted Republicans by playing late 1990s videos of Trump's most steadfast Senate defender, Lindsey Graham, and a member of his legal team, storied criminal defense lawyer Alan Dershowitz, both saying that abuse of power was indeed an impeachable charge.
BIDEN AND UKRAINE
Following Nadler, another impeachment manager, Sylvia Garcia, methodically detailed how Trump's using the pressure of aid to get dirt from Ukraine on his potential 2020 reelection rival Joe Biden was done for purely political reasons, She insisted there was no evidence backing Trump's claims that he was legitimately probing corruption.
She played videos of Trump officials, including the head of the FBI, dismissing his claim that Ukraine helped Democrats in the 2016 election.
"Where did this theory come from? You guessed it: the Russians," Garcia said in the nationally televised hearing.
"What is so dangerous is that President Trump is helping them perpetuate this -- our own president is helping our adversary attack our processes."
And, in a surprise, Garcia picked through the connections that former vice president Biden and his son Hunter had with Ukraine -- the son had served on the board of a leading Ukrainian energy firm -- to demonstrate there were no grounds for any allegations of corruption against them.
