July 6, 2021 Samuel Corum/Getty Images (WASHINGTON) — While Capitol Police are marking six months since the Jan. 6 attack on the U.S. Capitol by touting changes the agency has made to better prepare for such incidents, Congress continues its push for further investigations into the deadly incident. In a letter released by the Capitol Police Tuesday morning, acting Capitol Police Chief Yogananda Pittman paid tribute to the officers who lost their lives defending the Capitol in January and charted a path forward for the agency. “We will never forget USCP Officers Brian Sicknick and Howie Liebengood, who died after the attack, nor the sacrifices of the nearly 150 law enforcement officers who were injured,” she wrote. “Throughout the last six months, the United States Capitol Police has been working around the clock with our Congressional stakeholders to support our officers, enhance security around the Capitol Complex, and pivot towards an intelligence-based protective agency.”
