Innovation that excites!
I scream. You scream. We all scream for ICE CREAM CONES.🍦On this day in 1924, Carl R. Taylor patented an ice cream cone rolling machine (No. 1,481,813), automating the process of shaping flat wafers into perfectly formed cones.

Last April, OMB issued guidance to accelerate Federal AI adoption by removing barriers to innovation and empowering agency AI leaders. Federal CIO @GregBarbaccia & team have delivered and agencies have been hard at work. Under President Trump, AI works for the AMERICAN PEOPLE.
Today, Federal agencies began releasing their 2025 AI Use Case Inventories. This is American AI leadership in action! In the coming days, my team will post a consolidated Federal inventory. I am looking forward to sharing some of my favorite use cases with all of you!
