This NPR Up First news podcast covers three main stories: the narrow passage of a Republican budget plan including significant tax cuts and spending reductions; the ongoing conflict between the Trump administration and Elon Musk's involvement in government restructuring efforts; and the escalating battle against a highly contagious bird flu strain impacting the poultry industry. The budget plan, passed with only one dissenting Republican vote, initiates a lengthy reconciliation process in Congress. The White House denies Musk's authority despite his actions, creating internal conflict. Finally, the bird flu outbreak is proving difficult to contain, leading experts to suggest poultry vaccination as a new approach. The podcast highlights the political maneuvering surrounding the budget and the challenges of managing conflicting authorities within the government.
