LOS ANGELES, Feb 17 — US television presenter Savannah Guthrie pleaded with her mother’s kidnappers to “do the right thing,” while President Donald Trump said Monday he still hopes for a good outcome in a case that has baffled police and gripped the nation.

Guthrie, co-host of the “Today” show on NBC News, issued a video appeal on social media late Sunday hoping to address her mother’s abductors directly.
