“We aren’t finished yet,” House Speaker Nancy Pelosi told reporters Thursday. “As I said to the president, if you have any information that is exculpatory, please bring it forward, because it seems that the facts are uncontested as to what happened.”

Monday could represent a key decision point on that issue.

A U.S. judge is expected to rule on whether former White House Counsel Don McGahn must answer questions from the House Judiciary Committee, which could become a precedent for resolving related disputes between congressional Democrats and the White House over other witnesses. However that ruling goes, it isn’t likely to head off months of court fights over subpoenas that could go all the way to the Supreme Court.

“We cannot be at the mercy of the courts,” Pelosi said. “The courts are very important in all of this, those cases will continue. But I have never said we cannot proceed without the courts because that’s a technique on the part of the administration — just keep ratcheting up to a higher court.”
