The Department of Homeland Security’s chief watchdog scrapped its investigative team’s effort to collect agency phones to try to recover deleted Secret Service texts this year, according to four people with knowledge of the decision and internal records reviewed by The Washington Post.

In early February, after learning that the Secret Service’s text messages had been erased as part of a migration to new devices, staff at Inspector General Joseph V. Cuffari’s office planned to contact all DHS agencies offering to have data specialists help retrieve messages from their phones, according to two government whistleblowers who provided reports to Congress.

But later that month, Cuffari’s office decided it would not collect or review any agency phones, according to three people briefed on the decision.

The latest revelation comes as Democratic lawmakers have accused Cuffari’s office of failing to aggressively investigate the agency’s actions in response to the violent attack on the Capitol by supporters of then-President Donald Trump on Jan. 6, 2021.
