Experts have been warning for months that deepfakes and AI-generated content have the potential to wreak havoc on the 2024 election by persuading voters of things that aren't true — and undermining confidence in things that are.

• It's already happening.

📞 Driving the news: Some New Hampshire voters have been getting robocalls from a fake Joe Biden, encouraging them not to vote in tomorrow's primary.

• It's not Biden. But it sounds like him, down to using the word "malarkey." Some voters believed the president was calling them, NBC News reports.
• It's unknown who did it.

🚫 Separately, OpenAI shut down a tool created by supporters of long-shot Democratic candidate Dean Phillips. "DeanBot" used ChatGPT to simulate the experience of chatting with Philips.

• ChatGPT's terms of service prohibit political campaigning.

Almost 60% of the continental U.S. was covered in snow last week — the highest total in about 20 years, Axios' Ben Geman and Andrew Freedman report.

• Some of the snow fell in areas not typically accustomed to it: Nashville saw 7.6 inches for the month, most of it in one day. That's more than New York City saw for the whole month.
• Portland, Oregon, experienced a deadly ice storm that cut power to some neighborhoods for days.

😎 What's next: This cold snap is about to end. February will bring milder-than-average temperatures to much of the U.S.

The Pentagon today identified two Navy SEALs who went missing at sea earlier this month and were pronounced dead over the weekend.

• Navy Special Warfare Operator 1st Class Christopher Chambers, 37 (above left), and Navy Special Warfare Operator 2nd Class Nathan Gage Ingram, 27, were reported missing Jan. 11.

The two vanished during a raid in which the U.S. military seized a cache of Iranian-supplied missile parts and other weaponry bound for Houthi rebels in Yemen.

• President Biden said in a statement: "Jill and I are mourning the tragic deaths of two of America's finest — Navy SEALs who were lost at sea while executing a mission off the coast of East Africa last week. ... These SEALs represented the very best of our country, pledging their lives to protect their fellow Americans."
