Tonight, the disaster unfolding across the south, hundreds of thousands without power in dangerously cold weather.

The death toll rising and the temperatures are set to plunge even lower.

Car after car sliding off an icy road, piling up in a ditch, an arena roof collapsing under heavy snow.

electricity and pipes bursting inside the home of a family we introduced you to last night,

how they're surviving. Plus, we're tracking a bomb cyclone, the areas that could see even more

snow. The new video just in showing ICU nurse Alex Pretti in an altercation with federal officers

days before he was killed.

Plus, the two officers involved in the deadly shooting now placed on leave.

And the attack on Congresswoman Ilhan Omar, what we just learned was sprayed on her.

Also tonight, the man accused of murdering his wife so he could be with the family's au pair testifying in his own defense.

You'll see that husband take the stand, what he told the jury. FBI agents raiding a Georgia

infectious outbreak overseas deadlier than COVID. Airport screening passengers what were learning.

And there's good news tonight. Puppies rescued from a raging house fire and the dog finding

his forever home with the firefighter that saved him. Nightly
