House impeachment manager Adam Schiff just said, if the Senate does not allow witnesses and documents at trial, the chamber will be guilty of "working with the President to obstruct the truth from coming out."

He was just asked if he was worried that today's focus on Senate Majority Leader Mitch McConnell's proposed Senate rules and process "dilutes in any way the message you're trying to put out about what President Trump did."

Here's how he responded:

"No, because, look, this is part and parcel of an effort to cover up the President's misconduct. That was the whole object that is charged in Article 2 of the impeachment articles."

He continued: "And if the Senate and the Senate leadership will not allow the House to present its case, will not allow the calling of witnesses or presentation of documents, if Sen. McConnell makes this the first impeachment trial in history without witnesses or documents, it will not prove the President innocent — it will merely prove the Senate guilty of working with the President to obstruct the truth from coming out."
