WASHINGTON — Democratic House prosecutors argued Thursday in President Donald Trump’s impeachment trial that he was swept up by a “completely bogus” Ukraine theory pushed by attorney Rudy Giuliani and that led to his abuse of presidential power and then impeachment.

As the Democrats pressed their case for a second day, they displayed video images of the nation’s top FBI and Homeland Security officials warning the public off the theory that it was Ukraine, not Russia, that interfered in the 2016 election.

“That’s what Donald Trump wanted investigated or announced — this completely bogus Kremlin-pushed conspiracy theory,” said Rep. Adam Schiff, the chairman of the House Intelligence Committee who is leading the prosecution.

Trump is accused of seeking the investigation — and probes of political foe Joe Biden and Biden’s son — for his own political benefit while holding back congressionally approved military aid as leverage. Schiff said, “You can imagine what a danger that presents to this country.”

Trump is facing trial in the Senate after the House impeached him last month, accusing him of abusing his office by asking Ukraine for the investigations while withholding the aid from a U.S. ally at war with bordering Russia. Trump faces a second article of impeachment accusing him of obstructing Congress by refusing to turn over documents or allow officials to testify in the House probe.

Republicans have defended Trump’s actions as appropriate and cast the process as a politically motivated effort to weaken him in the midst of his reelection campaign.

The president’s defense waited its turn, which may come on Saturday.

Each side has up to three days to present its case. After the House prosecutors finish, likely Friday, the president’s lawyers will have as much as 24 hours. It’s unclear how much time they will actually take, but Trump’s team promises not only to defend the president but to take apart the Democrats’ case. The Senate is expected to take only Sunday off and push into next week.
