Senate majority leader Chuck Schumer announced that an agreement has been reached on rules for Donald Trump’s impeachment trial, which begins tomorrow.

“The structure we have agreed to is eminently fair,” Schumer said on the Senate floor. “It will allow for the trial to achieve its purpose: truth and accountability.”

Schumer said that the House impeachment managers and Trump’s defense team will each have 16 hours to present their arguments.

If the managers want to call witnesses in the trial, there will be a vote on whether to allow them to do so. Each side will also present a closing argument.

Senators will have time for questions and deliberations. The trial will go dark on Friday night to honor a request from Trump lawyer David Schoen that he be able to observe the Sabbath.

Senate minority leader Mitch McConnell agreed that the rules would ensure a fair trial.

“It will give senators as jurors ample time to review the case and the arguments that each side will present,” the Republican leader said.

Senate officials have released more details on the structure of impeachment proceedings, which will begin tomorrow. From the office of majority leader Chuck Schumer:

On Tuesday, there will be up to four hours equally divided between the impeachment managers and Donald Trump’s counsel to present arguments on the constitutionality of the trial. The Senate will then vote on whether it has jurisdiction to try the former president, and if a simple majority votes in favor (as expected), the trial will proceed.
Starting Wednesday at noon EST, there will be up to 16 hours per side for impeachment managers and Trump’s team to present their case. Each side must use their time over no more than two days, and each day’s presentation cannot exceed eight hours.

After both presentations, senators will have a total of four hours to question both parties.
There will then be two hours for arguments on whether to consider motions to subpoena witnesses and documents.
If the Senate votes in favor of subpoenas, both parties will then be allowed to depose witnesses and conduct discovery.

There will then be four hours of closing arguments before deliberations and a vote on the article of impeachment.
No trial proceedings will occur Friday after 5pm or on Saturday, but will continue on the afternoon of Sunday 14 February.
