COVER STORY:
"Mike Wallace is here" | Watch Video
Four words that struck terror into the hearts of shady businessmen and corrupt politicians – "Mike Wallace is here" – also comprise the title of a new documentary that depicts the dramatic life and career of the legendary CBS News correspondent, whose no-holds-barred interview style and indefatigable showmanship helped make "60 Minutes" must-see TV.  Rita Braver talks with filmmaker Avi Belkin (who was granted unprecedented access to CBS News' archives), and with Mike's son, "Fox News Sunday" anchor Chris Wallace, about building a career in the footsteps of a giant.

NATURE:  On the brink: The Endangered Species Act | Watch Video
Around the world, plant and animal species are going extinct at a rate faster than any time in human history.

But new regulatory changes to the Act are being finalized by the Trump administration, which may weaken its ability to protect wildlife and habitat, and – say wildlife advocates – speed extinctions. Conor Knighton reports.
