WASHINGTON (AP) — The U.S. House voted Wednesday to send two articles of impeachment against President Donald Trump to the Senate and approve House prosecutors for only the third impeachment trial in American history.

The nearly party-line vote moved Trump's impeachment from Speaker Nancy Pelosi's Democratic-run House to the Republican-majority Senate, where Trump expects quick acquittal, even as new evidence is raising fresh questions about his Ukraine dealings.

The vote was 228-193, coming at the start of a presidential election year and one month after the House impeached Trump alleging abuse of power over his pressure on Ukraine to investigate Democratic rival Joe Biden, using military aid to the country as leverage. Trump was also charged with obstructing Congress’ ensuing probe..

“We are here today to cross a very important threshold in American history,” Pelosi said, addressing the House before the vote.

“This is what an impeachment is about,'' she said earlier, announcing the prosecution team. “The president violated his oath of office, undermined our national security, jeopardized the integrity of our elections.”

Pelosi isn't the only Bay Area congresswoman with prior impeachment experience.

Rep. Zoe Lofgren, who has represented the South Bay for twenty five years, will be among the managers of the Senate's impeachment trial of President Donald Trump. Lofgren, while a member of the House Judiciary Committee, has publicly played a somewhat low-key role in the impeachment process thus far.

Lofgren's was a law student in 1974 when she worked as an aide to Rep. Don Edwards, whose seat won in 1995, as President Richard Nixon faced an impeachment.

In 1998, Lofgren was on the House Judiciary Committee, during the impeachment of President Bill Clinton.

Now, she's been tapped by Speaker Pelosi to take part in the Senate's upcoming impeachment trial.

The president's team expects acquittal with a Senate trial lasting no more than two weeks, according to senior administration officials unauthorized to discuss the matter and granted anonymity.

Trump opposes the calling of additional witnesses, and the officials said they expect the trial to conclude before Trump delivers his State of the Union address Feb. 4.

The seven-member prosecution team will be led by the chairmen of the House impeachment proceedings, Reps. Adam Schiff of the Intelligence Committee and Jerry Nadler of the Judiciary Committee, two of Pelosi’s top lieutenants for only the third presidential impeachment in the nation’s history.
