When Democrats won a majority in the House after the 2018 elections, impeachment talk grew louder and more, well, colorful. Sherman and Green reintroduced their article of impeachment, and that same day, Jan. 3rd, freshman Democrat Rashida Tlaib, at a MoveOn reception on Capitol Hill proclaimed Democrats would "impeach the motherf*****."
House Speaker Nancy Pelosi sought to tamp down pro-impeachment sentiments in the early days of the new Congress, calling it "divisive" and suggesting lawmakers should wait and see how the probe of Russian interference in the 2016 election led by Special Counsel Robert Mueller played out.
"He's just not worth it"
Pelosi repeated her opposition to impeachment in a Washington Post Magazine interview in March, words which Republicans have repeatedly pointed to in the months since. She said that "unless there's something so compelling and overwhelming and bipartisan, I don't think we should go down that path, because it divides the country," adding of Trump, "He's just not worth it."
Mueller report released
In April, Special Counsel Mueller's redacted report was publicly released. While it found no evidence that the Trump campaign actively conspired with Russia's efforts to interfere in the 2016 election, it did not exonerate the president from allegations that he obstructed the probe.
The findings gave more ammunition to Democrats who called for Trump's impeachment, including a growing list of those running for president.
Behind the scenes moves
Unbeknownst to lawmakers, the groundwork or casus belli of the impeachment inquiry was being laid over the spring and summer of 2019, after Congress approved some $391 million in military aid to Ukraine. On June 19, Trump started asking about the Ukrainian aid, and a few weeks later, officials have testified the aid was actually put on hold by the administration.
The Ukraine call
On July 25, Trump made his now infamous call to Ukrainian President Volodymyr Zelenskiy. According to a partial transcript, Trump tells him "I would like you to do us a favor though," and later asks that Zelenskiy "look into" activities by potential 2020 opponent Joe Biden and his son Hunter in Ukraine, as well as a discredited theory that Ukraine interfered in the 2016 election, not Russia.
The whistleblower
None of Trump's machinations over Ukraine aid, nor his requests of Zelenskiy were known publicly, until a still anonymous whistleblower came forward and filed a complaint on August 12th to the Senate and House Intelligence Committees. We later learned the whistleblower accused the president of "using the power of his office to solicit interference from a foreign country in the 2020 election."
But the whistleblower's complaint was withheld from Congress per an order from the newly named acting Director of National Intelligence. When House Intelligence Committee chairman Rep. Adam Schiff, D-Calif. discovered in September that a complaint had been filed, he threatened to sue the administration in order to force it to turn over the complaint.
News of Trump's phone call
On Sept. 20, the Wall Street Journal published a story alleging that "President Trump in a July phone call repeatedly pressured the president of Ukraine to investigate Joe Biden's son, according to people familiar with the matter." It was the first time the public found out the details of the July 25 phone call, which set in motion a series of events culminating in the impeachment vote.
Pelosi orders inquiry
On Sept. 24, Speaker Pelosi citing that report and others, said Trump is "calling upon a foreign power to intervene in his election. This is a breach of his constitutional responsibilities." She then announced the start of a formal impeachment inquiry. "The president must be held accountable," she said. "No one is above the law. " She said six congressional committees which have been investigating Trump's actions will continue under the auspices of the inquiry.
