Cummings has shown a continual willingness to butt heads with the White House since the Democrats have flipped the House, and on Wednesday, he continued down that path.
In a letter to Miller, Cummings wrote that he is inviting Miller to testify because “it appears that [he is] one of the primary moving forces behind some of the most significant — and in my view, troubling — immigration policies coming out of the Trump White House.”
Later in the letter, he cited some of those policies that he hoped Miller would explain, including “separating immigrant children from their parents at the border to deter them from coming to the United States, transferring asylum seekers to sanctuary cities as a form of illegal retribution against your political adversaries and firing top Administration officials who refuse to violate the law.”
Cummings acknowledged that Miller might not be too eager to testify but noted that Trump had said he was “in charge of handling all immigration and border affairs,” citing a Washington Post story from early April, and that Congress has the right to hear from somebody with such a role.
After Department of Homeland Security Secretary Kirstjen Nielsen left earlier this month, a source close to Nielsen suggested to Politico that Miller was one of the main catalysts behind her dismissal.
According to reports, Nielsen was at times hesitant to implement some of Trump’s crueler policies. According to CNN, her relationship with Trump boiled over after she refused to reinstate the family separation policy at the border and close the border at El Paso.
