Sharks have been swarming around southern California beaches for weeks. NPR wanted to know more about why, so we placed a call to Chris Lowe, a professor in marine biology and head of the Shark Lab at California State University at Long beach — or rather, we tried. Lowe was offshore on a boat trapping sharks to tag, and at the appointed time for our interview, Lowe had his hands full ... of shark.

Many Iranians spent the weekend in the streets celebrating the re-election of their president. Hasan Rouhani pledged to keep opening Iran to the world and to push for more freedom at home.

What difference does it make who's president of Iran?

It's fair to ask the question on this weekend of Iran's presidential election. After all, the president's title makes him sound like the top official, but he is not. Iran's supreme leader, Ayatollah Ali Khamenei, holds far more power.

Iran's presidential campaign has come to an end. Iranian election rules require a day of quiet today before actual voting begins tomorrow. The last night of campaigning, though, was not quiet at all. Our co-host Steve Inskeep reports from the road in Iran.

Nebraska Sen. Ben Sasse shares something in common with President Trump: both are serving in elected office for the very first time.

The similarities pretty much end there.

Sasse earned a doctorate in history. Before his election in 2014, he was a federal health official, and president of Midland University, which is linked with the Evangelical Lutheran Church.

When President Trump fired FBI Director James Comey on Tuesday, Sen. Ben Sasse of Nebraska was one of several Republicans in Washington voicing concern. As details unfolded throughout the week, Sasse, who sits on the Judiciary Committee, continued to call the timing of the firing "troubling," though he maintains there is not yet a need for an independent investigation or special prosecutor to look into Russian meddling in the 2016 election.
