From KCRW in Santa Monica and PRI, Public Radio International, this is To the Point.

Measuring Russian meddling in likes and retweets.

Hello again, I'm Arana Alney, and this is To the Point.

It's now common knowledge that Russia tried to influence last year's election in favor of Donald Trump. What was the role of social media? Facebook's Mark Zuckerberg

Scholar Norman Ornstein lays out the long view. First, this news update. President Trump has

temporarily lifted the Jones Act that restricted foreign ships from docking with relief supplies

in Puerto Rico. Here's the mayor of San Juan, Julian Cruz on CNN this morning.

It will allow Puerto Ricans to rebuild and to have a cost of living
