WASHINGTON (Reuters) — Text messages between two top security officials from the Donald Trump administration for a key period before the Jan. 6 attack on the U.S. Capitol are missing, the Washington Post said, citing unnamed people familiar with the matter.

Messages between acting Homeland Security Secretary Chad Wolf and acting Deputy Secretary Ken Cuccinelli, the department’s top officals at the time, were lost “in a ‘reset’ of their government phones when they left their jobs in January 2021,” the newspaper said.
