Good to be with you. I'm Tony DeCopold. The breaking news right now. Travel chaos, the major

American airports forced to close security checkpoints tonight as thousands of TSA officers quit or call out sick.

Entire airports could shut down next what the Trump administration is saying.

The other developing story tonight,

digging out and cleaning up after that massive cross-country storm, and now sub-freezing temperatures

moving in. And the war in Iran knew questions tonight about who's running that country,

as two more major regime leaders are killed in airstrikes, according to Israel.

And the political fight back here at home, a top Trump administration official resigns in

protest the president's response tonight. Also, day 45 of the search for Nancy Guthrie, the new

images from cameras on her property, what investigators are

now saying. Also that fireball over the U.S. and the sonic boom that followed it. What the

heck was it? And the grandparents' happy hour bill. What could possibly go wrong?

From CBS News headquarters in New York, this is the CBS Evening News with Tony DeCopold.

Good evening in the situation at American airports has gone from bad to worse over the past 24 hours.

Democrats are refusing to fund the Department of Homeland Security

unless Republicans agree to changes in immigration enforcement. But guess who's caught in the

middle? 50,000 TSA officers working without pay amid a partial government shutdown or not working at

all. About 10% of them have been calling out in recent days, and that leaves

more than 2 million airline passengers a day to deal with multi-hour security lines and

heightened concern about the risk of terrorism. Also late today, we learned that half the checkpoints

at Philadelphia International Airport will be closed effective tomorrow, and that's not all.

Senior Transportation correspondent Chris Van Cleave is all over this story for us.
