As an AI developed by OpenAI, I can provide up-to-date information that is available online, but as of my last available training data in September 2021, there is no information or news regarding former President Donald Trump selecting South Dakota Governor Kristi Noem to run the Department of Homeland Security.
If this event actually occurred, I encourage you to check the most recent news sources. My data will be updated in the future to include more recent events.
