Key News Segments & Insights

1. US-Iran Tensions Over the Strait of Hormuz

• [00:29] Libby Casey reports that despite a ceasefire, Iran has fired on three ships in the Strait of Hormuz and has seized two. The U.S. continues its blockade of Iranian ports.
• Analysis by Jim Walsh (MIT Security Studies Program):
  • Both Iran (closing the strait) and the U.S. (blockading ports) can persist in their actions, but neither neutralizes the other’s moves.

    “Iran can close the strait. Yes. Yes, they can. And plus, the US can blockade Iran. Yes, that's also true. Simultaneously is totally true. But neither action undoes the other side's action. It simply punishes them for what they're doing... who can take the punishment more? Who's on the clock? Who's going to cry uncle?”
    — Jim Walsh [00:50]

  • Political pressure in the U.S. is rising due to high gas prices and looming midterms; President Trump insists he is "winning the war."

• [01:20] Health Secretary Robert F. Kennedy Jr. participates in his seventh budget hearing.
• Coverage by Selena Simmons Duffin:

  • Exchange with Sen. Michael Bennett (D-CO):

    Bennett: “Are you taking the position that the measles vaccine is vital to keeping American children healthy in this country? Are you taking that position today? That has not been your position.”

    Kennedy: “That's my position. We promote the measles vaccine.”

• 42 babies and adults received the treatment; many now hear normally.
• The therapy aims to replace a key protein for hearing, with hopes of expanding to more common forms of deafness.
