Now that the rules are in place, opening arguments begin Wednesday in President Trump's impeachment trial.
Pennsylvania U.S. Senators Bob Casey and Pat Toomey spoke to WFMZ's Josh Rultenberg ahead of day two, and while both sounded a little tired after the first day lasted until 2 a.m., they promised they had what it takes to rebound for another day.
As far as how things are going so far though, neither is pleased.
"Honestly, Senator Schumer was never really interested in changing the rules here," said Toomey, a Republican.
Schumer, the Democratic minority leader, presented 11 amendments to Republican Majority Leader Mitch McConnell's rules, including a request for White House documents and witnesses.
However, each was set aside by a Republican majority.
"I don't understand why Republican senators and the president don't want fellow Republicans to go under oath," said Casey, a Democrat.
The rules look like this:
Both House managers and the president's lawyers will get 24 hours over three days each to make opening arguments.
Then, senators will get to submit written questions that can be read by the chief justice over a 16-hour period.
Finally, there will be four hours of debate on whether there will be any witnesses or additional documents presented to the Senate.
Casey and Toomey have different views on the package.
"If you're trying to arrive at the truth and have a fair trial, you should want people to put their hand in the air, take the oath and give truthful testimony. They seem to petrified, frightened of that," Casey said.
"The approach we've taken in adopting this rule package is very, very similar in all material respects to the Clinton impeachment," Toomey said.
He notes that he will decide after both sides present their cases on whether he wants to hear from more witnesses or see more documents. Two of his Republican colleagues have signaled they would like more and a third could do so as well.
The Senate reconvenes Wednesday afternoon with House managers starting their opening argument.
