Probe widens into Homeland Security watchdog's role in missing Secret Service Jan. 6 texts - The Washington Post

Cuffari waited months to disclose to Congress that his office had discovered the deletions and did not press Homeland Security officials to explain why they did not preserve the records. The Secret Service later provided the House committee investigating the Jan. 6 attack with thousands of records after reviewing its communications databases from the time of the attack, but nearly all of the records had been shared previously with Cuffari's office and Congress. 

Cuffari also blocked his own investigators from examining the Secret Service agents' phones. His actions prompted several congressional inquiries led by Democrats, who controlled the House last year.
