The big picture: Miller, who was invited to testify on May 1 on the Trump administration's immigration policies, is the latest White House official to reject a House testimony request in recent days. President Trump says he's against White House aides testifying before Congress. "We’re fighting all the subpoenas," he told reporters.

Justice Department rejects House Oversight subpoena on census citizenship question
Principal Deputy Assistant Attorney General John Gore will not comply with a subpoena from the House Oversight Committee compelling him to testify about the Trump administration's addition of a citizenship question to the 2020 census.
Driving the news: Earlier this month, the committee issued 3 subpoenas related to its investigation of the citizenship question, a controversy that has now been taken up by the Supreme Court. The Justice Department wrote in a letter that the committee's refusal to allow a DOJ lawyer to be present in the same room during Gore's deposition is unacceptable, and that Gore will not appear until that request is accommodated.
