Gov. Mike DeWine is urging President Donald Trump to relocate NASA's headquarters to Ohio.DeWine sent the letter to Trump on Friday, which was later shared on the governor's social media pages. In it, DeWine proposed the city of Cleveland as the space agency's new home."As Governor of Ohio, I am writing to strongly recommend that the National Aeronautics and Space Administration (NASA) Headquarters be relocated to the NASA Glenn Research Center," wrote DeWine. "This is an optimal time to move Headquarters out of the Washington, D.C. area, take advantage of a much more economical location, and gain significant efficiencies through co-location with a vibrant NASA Research Center."He continued, "Ohio is the birthplace of aviation, the heart of America's aerospace industry, and a critical hub for advanced technology, research, and manufacturing, including the Air Force Research Laboratory at Wright Patterson Air Force Base in Dayton and Ohio's newly designated Hub of Aerospace and Defense Innovation in Youngstown. This move would also align with the Administration's efforts to decentralize federal agencies. Cleveland, home to NASA Glenn Research Center, offers a significantly lower cost of living and operating expenses than Washington. Relocating NASA HQ to Ohio would result in substantial savings for taxpayers, while maintaining access to world-class aerospace research and development resources."DeWine concluded, "Further, Ohio's research and development capabilities are unmatched in the Nation. Moving the NASA HQ to Ohio would provide an exciting opportunity to capitalize on the synergy between the Air Force Research Laboratory, Air Force Materiel Command, and NASA Glenn Research Center, as well as commercial space companies testing at Armstrong Test Facility in Sandusky and the Nanoracks-Mitsubishi-Airbus-Palantir STARLAB effort in Columbus. Placing NASA HQ in Cleveland would reinforce Ohio as an international leader in both space exploration and aeronautics innovation. I urge the Administration and NASA leadership to place NASA Headquarters in Ohio -- the 'Heart of it All!'"The letter from DeWine comes as Trump has proposed relocating the headquarters of NASA and several other federal agencies based in Washington, D.C., en masse to various cities outside of the nation's capital. Both of Ohio's U.S. senators and 11 of Ohio's 15 congressional representatives have already thrown their support behind the proposal. This includes Sens. Bernie Moreno and Jon Husted, all 10 of the state's House Republicans, as well as Democratic Rep. Marcy Kaptur, who represents the Greater Toledo area.Cleveland-area Rep. Shontel Brown has not thrown her support behind the proposal. Neither has Cincinnati-area congressman Greg Landsman.At least three other states are also urging Trump to relocate NASA's headquarters to their respective states. This includes Texas, Alabama and Florida. Besides Ohio, Florida lawmakers are also mounting an especially aggressive push, with Florida U.S. Sens. Rick Scott and Ashley Moody going so far as to introduce legislation in the Senate this week to relocate NASA's headquarters to Cape Canaveral, the home of the Kennedy Space Center.In addition to NASA, Trump also is looking into relocating almost all other federal agencies outside of Washington, D.C. This led to a memo that the Office of Personnel Management sent last month to the heads of all federal agencies asking them to consider submitting headquarters relocation plans outside of Washington, D.C., by April 14 if they believe that it would be more cost-efficient for their agency in the long term to do so. It is still unclear what, if anything, will become of those efforts.The overwhelming majority of federal agencies are based in Washington, D.C., as well as the two surrounding states of Virginia and Maryland. However, despite this, some federal agencies, such as the Centers for Disease Control and Prevention and the Bureau of Land Management, are already located outside of the Greater Washington, D.C., area.So far, despite the idea being floated, no agencies have actually been moved outside of Washington, D.C., during Trump's term.
