rain is moving offshore and leaving frigid air behind it. it's not just bitterly cold in the midwest, it's up and down the i-9 corridor. d.c., new york, in the teens tomorrow morning. the problem is, when you're waking up tomorrow, you'll see any water left over on the road and sidewalks freeze over. that can turn dangerous, fast. >> kait, thank you. and now to the wedding horror outside of los angeles. a tree falling over on a wedding party. here's clayton sandell. >> reporter: what started as a celebration on a happy day, taking a cruel twist. >> i saw a bunch of kids. they were just running for their lives. >> reporter: a group of kids and

adults in a wedding party, gathered at this park in whittier, california, saturday for pictures, when the large tree above them came crashing down. police and firefighters scrambled to rescue them, using cpr on one victim. and chainsaws to cut away heavy branches, as members of the wedding party waited and prayed. >> a lady with a little baby and she was screaming so i hold the baby and put it down, and he had a very big bump on his head. it was bleeding. they were both bleeding. >> reporter: one person was killed. five others injured and taken to hospitals, including a 4-year-old girl in critical condition. officials say they don't know exactly why it fell, but say california's years-long drought followed by heavy rains may have affected the tree's health. >> we've seen this happen throughout southern california, with the drought, that trees are stressed. and we did have a large amount of rain. so there's some reason that that tree failed. >> reporter: you can see what's

there are several more large eucalyptus trees in this park, and officials are shutting it down until they can be inspected. >> thank you. and president-elect donald trump and members of the electoral college, making it official tomorrow. and mr. trump denying claims that russian president vladimir putin was involved in hacking the election. >> reporter: with the electoral college set to vote tomorrow, trump pushing back. >> if there is this conclusive opinion, they should issue a report or stand in front of a camera and make

>> reporter: u.s. intelligence groups agree, russian president vladimir putin was directly involved. but trump continues to question if russia played any role at all. >> they have no idea if it's russia, china, or somebody. it could be somebody sitting in a bed someplace. >> reporter: but the clinton campaign says there's no debate.
