The first public impeachment hearing involving President Donald Trump happened Wednesday morning through the afternoon.
The inquiry will include three total public hearings from three State Department officials.
On Wednesday Bill Taylor, a top U.S. diplomat in Ukraine, and George Kent, a high-level department official, testified on Capitol Hill live on television.
Republicans remained poised to defend the president amid this probe from the House Democrats, saying there weren't first-hand accounts of anything related to Trump and Ukraine nor did they speak directly to the president himself.
Taylor, who was second to testify, told House Intelligence Committee Chairman Adam Schiff that during a lunch with Gordon Sondland, the U.S. ambassador to the European Union, his staff members overheard a conversation between Trump and another Sondland by phone, saying it sounded like the president cared more about the investigation into Joe Biden than Ukraine.
He also said it was "crazy to withhold security assistance for help with a political campaign" and it made "no sense" to withhold aid from Ukraine based on helping with a political campaign.
Schiff is leading the impeachment investigation and opened with statements about whether Trump used the highest office in the land for personal gain when it came to dealings with Ukraine. He said the answer "..to these questions would not only affect the future of this presidency but also the future of the presidency itself.."
Schiff also stressed he would protect the identity of the whistle blower.
Rep. Devin Nunes (R-Calif.) spoke after Schiff, blasting the inquiry as a politically orchestrated sham for television.
Kent was first to testify Wednesday, detailing the ouster of ambassador Marie Yovanovitch and interactions with Trump's lawyer Rudy Giuliani.
On Friday, the committee will hear from Marie Yovanovitch, a former ambassador to Ukraine.
The hearing comes after House Speaker Nancy Pelosi launched the official and formal impeachment inquiry against President Trump -- a probe to find out whether the president abused his presidential powers. In an Associated Press story, she said such actions would mark a "betrayal of his oath of office" and declared: "No one is above the law."All three of the officials have already testified behind closed doors, according to an Associated Press story. "The Constitution doesn't require a vote to begin impeachment."
Meanwhile, Trump has called the probe "illegitimate," a "witch hunt" and called his phone call with the Ukranian president "perfect."
