“These are the weakest articles of impeachment that have ever been passed in any presidential impeachment,” one official said. “They state no violation of a crime, no violation of any law. And the idea that it is obstruction of justice, obstruction of Congress for the president to assert constitutionally grounded privileges that protect the separation of powers is absurd. We think that these articles fail on their face.”

“We’re prepared,” the official continued. “We have been ready and are ready to get things moving in the Senate because the facts overwhelmingly show that the president did nothing wrong. And we’re happy now that we’re going to have a chance to vindicate the president and get this process behind the country so that the American people can move on and stop having time wasted by House Democrats with their obsession to try and attack the president.”

The Senate is expected to vote on initial guidelines for the trial that are “very similar” to the ones used in the trial of President Bill Clinton in 1999, Senate Majority Leader Mitch McConnell (R-Ky.) has said. The guidelines would have both sides argue their cases before senators submit written questions. Only then would they vote on whether to call witnesses.

“We don’t think that there’s going to be any need for witnesses in this trial,” an administration official told reporters. “I think that if the Senate decides to adopt similar procedures to the Clinton trial—which seems to be a possibility and seems to be logical; all 100 senators agreed on it, at that point—it allows the senators to hear presentations and then decide whether they need to hear anything else. And we think, at that point, they wouldn’t need to hear anything else because this is an extraordinarily weak case for the House managers.”

The House managers were appointed on Jan. 15. Later in the day, the Democrat-controlled body voted to send the impeachment articles to the Senate and the managers walked the articles over to the Senate.

GOP senators said this week that there isn’t enough support to outright dismiss the articles of impeachment, which requires a simple majority. A removal from office, or conviction, requires a super-majority of 67 votes. One administration official said that it would be appropriate to dismiss the articles because they’re “so weak, that, on their face, if this were a court proceeding, they’d be subject to dismissal.”

The administration, though, is going forward with the defense of Trump. Officials believe the trial will wrap up fairly quickly, after senators have said it could last up to to six weeks.

“I think it’s extraordinarily unlikely that we’d be going beyond two weeks,” an official said after being asked if Trump would still give his State of the Union in early February if the trial was still going on.

“We think that this case is overwhelming for the president, and the Senate is not going to have any need to be taking that amount of time on this.”
