 After politics now, former President Donald Trump was out in the heat last night in Florida at a rally at one of his golf courses there. And in front of the overheated crowd, he took aim at President Biden's health and issued a new debate challenge. Meanwhile, President Biden gave a major speech to NATO in Washington yesterday as he tries to show he has the energy to keep doing this job. Our team is covering both sides of that story. But we're going to start with Caitlin Huey Burns, who's at the Trump rally or was last night there in steamy Miami. Caitlin, good morning to you.
