In the day's other headlines, in Berlin, there were more talks today on how to end the war in Ukraine.

Ukrainian president, Vloadi Mir Zelensky, President Trump's special envoy, Steve Whitkoff,

and Trump's son-in-law Jared Kushner met for five hours and are set to meet again on Monday.

Earlier, Zelensky appeared to be willing to abandon his goal of NATO membership if he got security guarantees.

Tomorrow, the group will be joined by European leaders.

In Gaza, large crowds gathered for the funeral of a top Hamas commander who was killed in an Israeli air strike outside Gaza city.

Israel said Ra'ad Sad had been trying to rebuild Hamas in violation of the

ceasefire agreement. He was also believed to have been the last remaining living architect of the

October 7th attacks. Hamas said it had named a new commander. And it will be a frigid start to the

work week for many across the country.

The National Weather Service forecasts an Arctic blast will plunge temperatures in the east and bring more snow to the Great Lakes.

Freeze warnings are expected as far south as Georgia.

At the Pacific Northwest, heavy rains are expected to return tomorrow

and could lead to flash flooding in that already saturated area.
