"We write to seek your voluntary cooperation in advancing our investigation", Select Committee Chairman Bennie Thompson said in the letter to Jordan. "We understand that you had at least one and possibly multiple communications with President Trump on January 6th. We would like to discuss each such communication with you in detail".
The Select Committee is seeking details about Jordan's communication with individuals in the Willard War Room near the White House, the Trump legal team, and with White House personnel and others involved in organising strategies for the January 6th gathering, the letter said.
The Select Committee is asking Jordan to testify on January 3rd, 4th, or 10th, the letter noted.
Jordan is just the latest in a series of high-ranking officials who have been asked to appear before the House panel. Earlier this week, US Rep. Scott Perry (R-PA) declined a request from the committee shortly after reports revealed that Infowars host Alex Jones and former National Security Adviser Michael Flynn had both filed lawsuit to oppose January 6th subpoenas.
