(CNN) – “Stop the Steal” frontman Ali Alexander turned over thousands of text messages and communication tapes to the House special committee investigating January 6 that include his interactions with members of Congress and former President Donald Trump’s inner circle leading to the riot, according to a court document submitted Friday night.

The revelations emerged from Alexander’s challenge to the committee’s efforts to obtain his phone records directly from his telecommunications provider.

“Alexander received a notice from Verizon indicating that the select committee had assigned Verizon for nine categories of information associated with Alexander’s cell phone number,” the file said. “The data sought is irrelevant to the investigation and sweeps away privileged communications between Alexander and the clergy, Alexander and those he spiritually advises, and Alexander and his respective attorneys.”

The move comes more than a week after Alexander spent several hours testifying with committee organizers. It also highlights the wealth of information that committee staff must sift through and analyze.

Alexander is a central figure for investigators seeking to understand how the January 6 rallies were funded, organized, promoted and ultimately escalated into an attack on Capitol Hill meant to stop the certification of electoral votes for Joe Biden’s presidency.

Alexander provided communications with Republican Representative Paul Gosar of Arizona, possibly GOP Representative Mo Brooks of Alabama, and detailed a call that Alexander said included anonymous members of Congress, the file said. .

On November 24, he provided the committee with more than 1,500 mobile messages “sent and received by him and those he corresponded with,” the file said.

“Mr. Alexander said he had had telephone conversations with Representative Brooks’ staff about a ‘Dear Colleague’ letter and how his activists might be of assistance,” the file reads. “Mr. Alexander believes he exchanged a text message with Representative Brooks, the contents of which he provided to the committee. “

Alexander also told the committee about a “short and pleasant call” he had with Kimberly Guilfoyle, a fundraiser and girlfriend of Trump’s son Donald Jr., in which the two discussed the elections in courses in Georgia and the 2022 Republican primaries, according to the filing.

Guilfoyle also thanked Alexander for “being a leader in voting rights and for creating the ‘Stop the Steal’ movement,” the file said.

Alexander challenges the validity of the committee’s authority, citing what he believes to be the politically unbalanced makeup of seven Democratic lawmakers and just two Republicans, according to the filing.

“President (Nancy) Pelosi appointed only nine members to the select committee: seven Democrats and two Republicans,” the file said. “The select committee, however, is not an authorized congressional committee because it does not comply with its own authorizing resolution, House Resolution 503.”

Further, Alexander argues that the subpoena for his data is too broad, writing in his complaint that “the breadth and invasiveness of Verizon’s subpoena also gave the appearance of a criminal investigation, not a legislative fact-finding mission “.

“Mr. Alexander has a reasonable expectation of the privacy of his cell phone and personal data,” the file said. “He remains a private citizen who has never served in government. He has reasonable expectations of confidentiality and is not subject to any required record keeping regulations like government officials or government employees.”

Alexander’s group had a permit on Jan.6 to hold a rally on the northeast side of the Capitol grounds, but claim it played no part in the violence that took place on Jan.6.

Alexander previously claimed he worked closely with members of Republican Congress to plan the rally on Capitol Hill on January 6. In several Periscope videos in December 2020, Alexander said he was in contact with Gosar, Brooks and Arizona Rep. Andy Biggs about the rally. which preceded the riot.

Alexander last week denied working with lawmakers to attack the Capitol and claimed his evidence in fact exonerated those members.

The committee last week issued six more subpoenas for people involved in planning the January 5-6 rallies leading up to the violent attack, including those who coordinated the planning for the rally directly with Donald Trump.
