John Sakellariadis / Politico : President Trump renominates Sean Plankey to be the next director of CISA, which has been running without a full-time chief since Trump's return to office —  Sen. Rick Scott (R-Fla.) scotched Plankey's confirmation in 2025, reportedly due to a Coast Guard ship-building contract.
