Social Media Buzz: From Sen. John McCain To Elon Musk Announcement

Sen. John McCain's brain cancer diagnosis this week has sparked a huge outpouring online, with many people sharing a 2008 video of him during his presidential campaign.

Here & Now's Robin Young speaks with Al Jazeera English's Femi Oke (@FemiOke) about that, and about the announcement Thursday from Tesla's Elon Musk that he got "verbal govt approval" for what he calls a hyperloop, or high-speed train in a tube, that could travel from Washington to New York City in less than 30 minutes.
