The White House pursued a "months-long effort" involving top officials to extract concessions from Ukraine's government aimed at helping President Trump's reelection in 2020, House Democrats charged in a new report.

After two weeks of public hearings, the House impeachment inquiry into President Trump is approaching its next stage: lawmakers are now writing a report that could lead to articles of impeachment.

Fiona Hill, who served as the top Russia expert on the National Security Council before resigning last summer, criticized Republicans on the House Intelligence Committee for advancing theories that Ukraine, and not Russia, interfered with the 2016 presidential election.

Testifying on the third and final day of impeachment hearings before the panel this week, Hill said, "I would ask that you please not promote politically driven falsehoods that so clearly advance Russian interests."

The Senate is beginning a trial on whether or not to remove President Trump from office, a little over a month after the House voted to impeach him.

Each week — and some days, it seems, each hour — brings more clarity to the picture of the Ukraine affair and the political crisis it sparked in Washington over impeachment.

The rapidly unfolding Ukraine scandal has kicked impeachment investigations into high gear, with Democratic leaders in Congress now saying it will take just a number of weeks to consolidate findings from multiple House committees.

"This is not going to require months and months and months of hearings," says Rep. David Cicilline, D-R.I., who spoke with NPR on Saturday.
