Just because your office is deserted for the holidays doesn’t mean all’s quiet on the western front. Trump is still tweeting, and relations seem to be ever-warming between the president-elect and Vladimir Putin, even when they’re one-upping each other on building more nuclear weapons.

Admittedly, these aren’t the easiest topics to swallow at a dinner table packed with relatives of varying political stripes. But fear not! There’s always drug price gouging and KGB ties to Trump’s national security adviser to discuss. —Megan Hess

Donald Trump escalated his remarks about the U.S. nuclear arsenal on Friday, telling a TV host off-air that he isn’t concerned about triggering an arms race with Russia or other adversaries, a day after a tweet that appeared to reset America’s posture on atomic weapons.

A Trump aide partnered with a firm run by a man with alleged KGB ties. Donald Trump’s national security adviser, Michael Flynn, collaborated this year with a controversial tech company co-run by Subu Kota.

Almost everyone wins when it comes to referral hiring: The applicant is more likely to get the job, companies cut hiring costs, and the original employee who did the referring often gets a bonus. It’s a nice, closed-loop system—that is, unless you don't have the right network to get the job. Referral hiring isn't great for diversity.

On Nov. 9, Hillary Clinton voters ate their grief. The morning after the 2016 vote, aggrieved Clinton supporters did what Americans do best: They ate. Apps like Lose It!, which helps users track their daily food intake, and Caviar, a meal-ordering app, have the data to back that up.
