Stephen Miller , former Trump advisor, filed suit Wednesday to stop the House investigation into the Jan. 6th riot. He argued that his siblings and parents could be involved in the search since he is still on the family plan.

Miller, 36, claims that the subpoena of T-Mobile to obtain his phone records by the committee is “overbroad” in papers filed in Washington, D.C.

According to the filing, the subpoena is for “information regarding Mr. Miller’s cell phone number for the three month period November 1, 2020 through January 31, 2021.”

Miller, who was the architect of the Trump administration’s family separation policy at its southern border, accused committee of “improperly trying to obtain information” on “free speech, association activities that are protected under the First Amendment to U.S. Constitution.” Constitution.” Jan. Jan. 6. The suit states that “there are no facts which show that Mr. Miller was involved in what occurred there or engaged in any unlawful attempts to interfere with peaceful transfer of power the the Biden administration.”

Miller and Carron Drive Apartments LP filed the suit. Miller and Carron Drive Apartments LP is a California business that, according to court filings, subscribes for a T-Mobile family account for Miller, his siblings, and their parents. According to the suit, Miller has been on the account for “at least the last 10 years.”

The filing states that “Carron Drive, and Mr. Miller, have filed this Complaint in order to seek this Court’s protection against the Select Committee’s intrusive, unjustified attempt at violating the privacy rights Mr. Miller and potentially other Miller family members have under the Family Plan Account.”

It also claims that the records sought would include “those evidencing sensitive and personal communications Mr. Miller had between medical professionals and his family concerning his wife and newborn girl.”

However, the suit states that the subpoena to the committee is for records that would reveal who Miller was talking with, and how long, but not the content of the conversations.

A request for comment was not received by the committee immediately.

This legal action is just one of many filed by Trump supporters to stop the committee from obtaining phone records.

Other plaintiffs include Roger Stone , former campaign advisor , Trump’s social media director Dan Scavino and former White House chief staff Mark Meadows.

Miller’s suit states that, unlike many other legal challenges, he “does not dispute the legitimacy” of the Select Committee investigation into the facts surrounding the events at Capitol in Washington on January 6, 2021. The suit, like the others, claims that the subpoena of his records is not related to or in support of a legitimate task for Congress and that it violates his constitutional rights.

It asks for a declaration declaring that the subpoena is “unenforceable.”
