The provided news articles focus on separate incidents: the search for Savannah Guthrie's mother, a hypothetical 'sonic weapon' used in a fictional abduction of Nicolas Maduro, and criticism of the US agriculture secretary's meal suggestion. None of these articles mention NewsNation or provide any information about the organization. Therefore, it's impossible to create a summary about NewsNation based solely on these articles. To provide an accurate summary, articles that specifically mention NewsNation are required.
