A federal judge ruled late Tuesday that an email that the judge said contains evidence of a possible crime must be turned over to the committee by Wednesday.
The judge ordered Eastman to turn over the documents by 2 pm. More than 400 are protected under attorney-client privilege.
The crime-fraud exception is when a document that would otherwise be covered under attorney-client privilege has to be turned over.
A negative court ruling could violate the law if it showed that Trump planned to delay or stop the electoral vote.
According to the documents, Trump and Eastman planned to disrupt Congress' electoral vote counting as early as December 7, 2020, when Trump forwarded a memo explaining why January 6 was the "hard deadline" that was critical to the result of this election.
Other documents being handed over to the committee include documents related to the Trump campaign's "fake electors" scheme and emails related to multiple meetings with an unnamed right-wing group.
Carter had previously ordered Eastman to turn over other documents, including one in March that found Trump's efforts to overturn the election were more likely than previously thought.
Carter said that the January 6 plan was solidified by the email that had to be disclosed. The Trump legal team forged ahead with a political campaign to disrupt the electoral count despite not seeking recourse in court. Lawyers can't avoid judicial review to overturn a democratic election.
The House January 6 committee will begin a series of public hearings on Thursday to show the evidence it has gathered over the court of the committee's investigation.
Carter noted that several of the emails were just news articles or photos and did not explain how they sought legal advice. Carter forced those documents to be disclosed because Dr. Eastman claimed that the photo was President Trump's handwritten note for anticipated litigation.
Trump was advised by a conservative legal scholar in the aftermath of the 2020 election, though it is not known when they became his client. He spoke at the January 6 rally. CNN reports that he invoked his Fifth Amendment rights against self-incrimination after being subpoenaed by the House. The State Bar of California is looking into whether his post- election efforts violated state law.
The lawyer who drafted the plan to overturn the election is under investigation.
A federal judge says that Trump is likely to have tried to obstruct the election.
John Eastman uses a Christian crowd funding site to raise money for his legal bills.
