WASHINGTON -- The words from one president to another, somewhat casual in tone, were not casual at all in meaning: "I would like you to do us a favor, though."
Those words have now prompted deployment of the ultimate political weapon, an impeachment process enshrined in the Constitution as a means other than the ballot to remove a president from office.
That was the favor.
And what in return?
Quid pro quo means something for something.
That Latin phrase is at the core of today's mountain of subpoenas, the pile of insider text messages that weren't supposed to come out, the tug of war between Congress and the White House over willing and reluctant witnesses and the blizzard of aggrieved Trump tweets.
This, as Democrats move closer to a Senate impeachment trial that would be only the third in the nation's history.
A familiar pattern is emerging. Trump, like Richard Nixon and Bill Clinton before him, is striking back at his accusers, though Trump does it with more bite, force and relentless volume. He also has near-lockstep support from his party, as Clinton did, and Nixon, until he didn't and resigned in disgrace.
Among underlings, loyalties fracture. Conspiratorial thinking, even paranoia, creeps in. Who is next to talk, stonewall, turn, quit? Who will break and when? Who won't break? Nixon was undone in part by Deep Throat. Trump thinks the Deep State is out to get him.
Trump, ever defiant, never contrite, insists he did nothing wrong, that his communication with the leader of a corruption-plagued country was appropriate and that the impeachment effort is a politically orchestrated hit by Democrats to nail him on Ukraine when they couldn't get him on Russia.
How we got here is something of a play in three acts, involving machinations by Ukrainians, Trump and Democrats in turn, with the fourth act to be written.
THE BLACK EARTH
A true if flawed democracy on Russia's doorstep, Ukraine in 2014 ushered out a pro-Russian leader who tolerated corruption and replaced him with an anti-Russian leader who tolerated somewhat less corruption.
Then in 2019 came Volodymyr Zelenskiy . The comedian and political novice proposed to govern with a straight face and an eye to making Ukraine more like its European neighbors to the west while ending the war against Russian-backed forces in the east.
He was counting on unflagging support from the U.S. Instead he got Trump, with his faith in Russia's good intentions and fixation on conspiracy theories against Democrats.
For Trump, the Bidens may have looked like easy prey. While Joe Biden was Barack Obama's vice president and counseling Ukraine's government on fighting corruption, the younger Biden was hired by Burisma, a Ukrainian natural gas company whose owner was feeling some heat.
By putting Hunter Biden on the board in spring 2014, Burisma's owner probably wanted to show the new Western-leaning Ukrainian government that powerful people in the West had his back.
Although no evidence of anything illegal emerged, it looked bad and caused some to question whether Burisma was buying influence with the Obama administration. In early 2016, Joe Biden pushed Ukraine to fire the prosecutor charged with investigating Burisma, except that he had stopped investigating.
What the U.S. and its European allies wanted was a Ukrainian prosecutor more committed to combating corruption, not less.
Trump also seemingly bought into a long-discredited conspiracy theory that connects Ukraine, not Russia, to the 2016 political interference and the hacking of the Democratic National Committee.
U.S. intelligence agencies attributed the hack to Russia. So did Robert Mueller, who as special counsel charged 12 Russian military intelligence officers. Even a former Trump homeland security adviser has urged the president to stop pushing the false story.
The day Zelenskiy was inaugurated, May 20, saw the abrupt departure of the American ambassador, a longtime diplomat who Trump apparently believed was undermining his efforts to push Ukraine to investigate the Bidens.
Trump's motive in recalling Marie Yovanovitch — he called her "bad news" — is now part of the impeachment inquiry. In her testimony in October, she %href—on(file:
