"Did the President Lie? Wasn't the President Fair in His Responses to the Muller Investigation?" Chamber General Counsel Douglas Letter told the U.S. Court of Appeals for the District of Columbia why the Chamber now needs access to grand jury materials that Mueller collected during his investigation.
But Trump told Mueller in writing his statements that he does not remember discussing WikiLeaks with Stone.
Gates' testimony added to Congress's "desire to see the material edited.
The question of whether Trump is obstructing justice, including a potential lie to Mueller, is intended to be part of a broader review of the Kama Judiciary Committee potential obstacles following Mueller's report: The Chamber has previously reviewed much of what Mueller wrote in his latest report, including parts preserved by the public.
But the Chamber failed to see what Manafort said before the big court Mueller apparently described in his report, Mueller's report details the grand jury details in connection with a sentence describing Manafort who spoke to Trump after the first issue of WikiLeaks in July 2016.
Manafort's situation shows so clear that there is evidence, very sad, that the president may have given incorrect answers, and that is a key part of the impeachment investigation, "the letter said Monday in the last words of its arguments before a panel of three judges.
Judge Judith Rogers on Monday expressed skepticism about the Justice Department's motives for withholding information about Manafort from the Chamber now.
"Why would the department not want to provide this information because it might show that he did nothing wrong? The chamber would not want to return an accusation when the evidence does not support it," she said of the impeachment investigation. Another judge in the court, Thomas Griffith, questioned why the Chamber needed the information. And a third judge, Neomi Rao, whom Trump has appointed, asked whether the courts should be involved in providing information to the Chamber that could influence the impeachment investigation.
The court case revolves around what federal investigative information should be able to access by the Chamber during impeachment and what federal courts can do in a dispute between the Chamber and the executive.
