The impeachment trial for President Donald Trump will not last longer than two weeks before he is acquitted, senior Trump administration officials predicted on Wednesday just before the House of Representatives voted to send articles of impeachment to the Senate.

White House officials insist the trial will move quickly and that Trump did nothing wrong when he withheld military aid from Ukraine in order to pressure the countrys president to open an investigation into former Vice President Joe Biden , Trumps potential 2020 rival for the presidency.

The reason it will not be a very long time is the facts are simple and the facts are on the presidents side, a senior administration official said on a briefing call with reporters, on condition of anonymity.

The White House also hopes its opposition to the calling of any new witnesses which Democrats want after the White House blocked testimony from notable officials during the Houses impeachment inquiry would also help lead to a swift conclusion to the trial.

It makes sense that the White House is so bullish about Trumps prospects in the Senate trial. Nearly all Senate Republicans have echoed the presidents talking points on his actions and impeachment. Senate Majority Leader Mitch McConnell (R-Ky.) said the House rushed Trumps impeachment with an incomplete case due to the Democratic Party s partisan rage. He said that he will not be an impartial juror during the trial.

Still, its possible four Republicans will choose to side with Democrats and call at least one new witness. That would most likely be former national security adviser John Bolton, who was reportedly opposed to the scheme to pressure Ukraine to investigate Biden, saying he did not want to be involved in a metaphorical drug deal planned by the presidents agents.

Bolton has said he was willing to testify to the Senate. But the president would likely invoke executive privilege to prevent Bolton from divulging any private conversations they had, senior administration officials said.
