Today on the Daily Scoop Podcast from the Scoop News Group, Katie Arrington lands in industry as CIO of Quantum Co. IonQ, and Sean Planky is renominated to lead CISA. It's Thursday, January 15, 2026. Welcome to the Daily Scoop Podcast, where you'll hear the latest news and trends facing government leaders. I'm the host of the Daily Scoop Podcast, Billy Mitchell. Thanks so much for joining me. And now let's dive into the day's top headlines. After leaving her role performing the duties of the Chief Information Officer for the Department of Defense last month, Katie Arrington has taken on a new position as CIO at Quantum Co. IonQ. Arrington will step into her new role Jan. 19, reporting to the company's COO and CFO inder Singh I andQ announced Wednesday. Kirsten Davies was nominated by President Donald Trump in May 2025 to be the Department of Defense's CIO, and it took most of the remainder of that year for the Senate to confirm her into the role. She was sworn in just before the Christmas holiday, at which point Arrington stepped away from her service to the pentagon. In joining IonQ, Arrington will serve on the company's executive team and as cio. Arrington will continue to support US Military from a different vantage, leading modernization and and security of IonQ's enterprise systems in support of its mission to deliver quantum capabilities to American warfighters. Before rejoining the Pentagon a year ago, then as deputy CIO for cybersecurity, Arrington had a previous stint as CISO in the Office of the Undersecretary of Defense for Acquisition and Sustainment, where she was largely responsible for the development of the Cybersecurity Maturity Model Certification, or cmmc, program. Now, in other news, President Donald Trump re nominated Sean Planky to lead the Cybersecurity and Infrastructure Security Agency on Tuesday after Planky's bid for the position ended last year. Stuck in the Senate, it's not clear whether or how Planky's resubmitted nomination will overcome the hurdles that left many observers convinced his chance of becoming CSA director had likely ended. But it does definitively signal that the Trump administration still wants Plaky to have the job. Plenki's nomination was included in a batch sent to the Senate announced on Tuesday. CISA spent all of 2025 under Trump without a permanent director. Trump nominated Planky, who held a couple cybersecurity roles in the first Trump administration, to lead CISA in March. He participated in a Senate Homeland Security and Governmental Affairs Committee hearing in July, then won approval from that panel the same month. But Senator Rick Scott, Republican of Florida, had placed a hold on Planky's nomination over a Coast Guard contract that the Homeland Security Department had canceled in part while he awaited confirmation. Planky had been serving as a senior advisor to the secretary for the Coast Guard. A spokesperson for Scott did not immediately respond to a request for comment. North Carolina's GOP Senate delegation also had placed holds on DHS nominees related to disaster aid to their state. Senator Thom Tillis, Republican of North Carolina, said last week that the holds would remain until Secretary Kristi Noem appeared before the Senate Judiciary Committee. A White House official had denied reports that Planky's nomination was all but over last year, saying that President Trump had been clear that he wants all of his nominees confirmed as quickly as possible, including Plenky, who he said would play a key role in ensuring a strong cyber defense infrastructure. When asked Wednesday at the Surface Navy Association National Symposium about what he was doing to convince senators to lift their holds, Plenky answered, quote, the administration, the White House has to say that this is a priority of us.
