Some of the organizers who planned the rally that took place on the White House Ellipse on Jan. 6 allegedly used difficult to trace burner phones for their most “high level” communications with former President Trump’s team.

Kylie Kremer, a top official in the “March for Trump” group that helped plan the Ellipse rally, directed an aide to pick up three burner phones days before Jan. 6, according to three sources who were involved in the event. One of the sources, a member of the “March for Trump” team, says Kremer insisted the phones be purchased using cash and described this as being “of the utmost importance.”

The three sources said Kylie Kremer took one of the phones and used it to communicate with top White House and Trump campaign officials, including Eric Trump, the president’s second-oldest son, who leads the family’s real-estate business; Lara Trump, Eric’s wife and a former senior Trump campaign consultant; Mark Meadows, the former White House chief of staff; and Katrina Pierson, a Trump surrogate and campaign consultant.
