This NPR "Up First" podcast episode for June 18th, covers two main news stories: Firstly, it examines President Trump's evolving stance on potential military involvement in Iran, particularly regarding its nuclear program, and the pushback he's receiving from some of his allies who advocate for an "America First" approach. Secondly, the episode discusses the conflicting messages from the Trump administration regarding immigration enforcement in industries like agriculture, where there's tension between the need for immigrant labor and the desire for increased deportations, leading to uncertainty among employers and workers.
