The second day of the public hearing in the impeachment inquiry against President Donald Trump began Friday morning on Capitol Hill.

Former U.S. ambassador to Ukraine Marie Yovanovitch is expected to testify Friday. More witnesses will make their appearances next week.

The Wednesday morning testimonies from Taylor and George Kent, a senior State Department official in charge of Ukraine policy, came during a particularly dramatic chapter in Trump's presidency and right before the start of the holidays, making the hearing feel at times like the prologue to a buzzy season finale.

The impeachment inquiry, led by congressional Democrats, is heating up and could culminate in a House vote before the end of the year — weeks before the first primary votes are cast in the already fevered 2020 presidential election.

The first few hours of the hearing, while largely focused on the historical context around the U.S. relationship with Ukraine and anti-corruption efforts there, featured a few memorable moments that are sure to volley across social media echo chambers.
