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 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."
Trump, during an event at the White House, rejected the charges as a "hoax."
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.
All but one Democrat, Rep. Collin Peterson of Minnesota, voted to transmit the articles. All Republicans voted against. One former Republican-turned-independent, Rep. Justin Amash of Michigan, joined Democrats.
The top Republican in the House, Kevin McCarthy of California, said Americans will look back on this "sad saga" that tried to remove the president with the "weakest case."
Later Wednesday, the House managers were to walk the articles across the Capitol to the Senate in a dramatic procession. The Senate trial is set to start Thursday.
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.
Ahead of Wednesday's session, Schiff released new records from Lev Parnas, an associate of Trump's lawyer Rudy Giuliani, about the Ukraine strategy including an exchange with another man about surveilling later-fired Ambassador Maria Yovanovitch.
Schiff said the new evidence should bring more pressure on Senate Majority Leader Mitch McConnell, who is reluctant to allow witnesses to testify.
"If McConnell makes this the first trial in history without witnesses, it will be exposed for what it is and that is an effort to cover up for the president," Schiff said.
McConnell opened the Senate dismissing what he called a rushed impeachment that is more about the politics of Democrats who don't like Trump than the charges against him.
"This isn't really about Ukraine policy or military money," McConnell said. "This has been naked partisanship all along."
During Pelosi's press conference announcing managers, Trump tweeted that impeachment was "another Con Job by the Do Nothing Democrats. All of this work was supposed to be done by the House, not the Senate!"
The managers are a diverse group with legal, law enforcement and military experience, including Hakeem Jeffries of New York, Sylvia Garcia of Texas, Val Demings of Florida, Jason Crow of Colorado and Zoe Lofgren of California.
McConnell, who is negotiating rules for the trial proceedings, is under competing pressure from his party for more witnesses, from centrists who are siding with Democrats on the need to hear full testimony and conservatives mounting Trump's defense.
Senate Republicans signaled they would reject the idea of simply voting to dismiss the articles of impeachment against Trump, as Trump himself has suggested. McConnell agreed he does not have the votes to do that.
''Our members feel we have an obligation to listen to the arguments," McConnell said Tuesday.
A mounting number of senators say they want to ensure the ground rules include the possibility of calling new witnesses.
Sen. Susan Collins of Maine is leading an effort among some Republicans, including Mitt Romney of Utah and Lisa Murkowski of Alaska for votes on witnesses.
Romney said he wants to hear from John Bolton, the former national security adviser at the White House, who others have said raised alarms about the alternative foreign policy toward Ukraine being run by Giuliani.
Democrats have been pushing Republicans to consider new testimony, arguing that fresh information has emerged during Pelosi's monthlong delay in transmitting the charges.
Republicans control the chamber, 53-47, and are all but certain to acquit Trump. But it takes just 51 votes during the trial to approve rules or call witnesses. Just four GOP senators could form a majority with Democrats to insist on new testimony. It also would take only 51 senators to vote to dismiss the charges against Trump.
At Tuesday's private GOP lunch, Sen. Rand Paul of Kentucky warned that if witnesses are allowed, defense witnesses could also be called. He and other Republicans want to subpoena Biden and his son, Hunter, who served on the board of a gas company in Ukraine, Burisma, while his father was vice president.
McConnell prefers to model Trump's trial partly on the process used for President Bill Clinton's impeachment trial in 1999. It, too, contained motions for dismissal or calling new witnesses.
McConnell is hesitant to call new witnesses who would prolong the trial and put vulnerable senators who are up for reelection in 2020 in a bind with tough choices. At the same time, he wants to give those same senators ample room to show voters they are listening.
