Government shutdown updates: Senate vote marks step towards ending federal shutdown

Transportation Secretary Sean Duffy, who previously served as a member of Congress, slammed senators for going home as the shutdown continues.

"When I was in Congress, we had shutdowns. I stayed here for a month. I didn't fly home. I sat in my office working on deals, working on solutions. Why are senators going home? If you can vote 14 times to keep the government shut down and create this gridlock in our airports, and you're going to go home -- they should sit here like Americans sit in airports. They shouldn't sit in their offices. They should sit in the Senate and figure out how they're going to come up with a deal to open this back up and not use the American people as leverage," Duffy said at Washington's Reagan National Airport on Friday.

Duffy encouraged airline travelers experiencing delays or cancellations to call their representatives.

"To those passengers that are upset, listen, call your Democrat senator. Fourteen times they voted no to open up the government," he said.

Transportation Secretary Sean Duffy visited Washington's Reagan National Airport on Friday morning as flight reductions take place at airports across the country.

"I want to hear about the passenger experience. What can we do better and get their feedback? I think that's always important to hear from the experience of the American traveling public," Duffy told reporters.

Duffy defended the administration's decision to direct airlines to cut 10% of their flights at the high-impact airports no later than Nov. 14.

"It is not a science. It is an art that we're trying to deploy to keep people safe in the airspace ... and we're trying to prevent the pressure that we now see building in the system," he said.

"These are the recommendations that have come from the FAA safety team, but you want us to look at what we see with regard to data and make really good decisions to keep people safe. That's what we've done today. I think it's the right decision," Duffy added.

President Donald Trump is once again calling on Senate Republicans to "Terminate the Filibuster" as the government shutdown stretches on, in multiple social media posts on Friday morning.

"Just say NO (Nuclear Option!). TERMINATE THE FILIBUSTER!," Trump wrote in one post.

The posts come ahead of a 15th vote on government funding in the Senate, though exact timing on the vote is unclear.

After a judge's ruling requiring the administration to make a payment to fully fund SNAP for the month by Friday, Vice President JD Vance argued courts shouldn’t be allowed to direct the administration on how to "triage the situation" amid the government shutdown.

"It's an absurd ruling, because you have a federal judge effectively telling us what we have to do in the midst of a Democrat government shutdown, which what we'd like to do is for the Democrats to open up the government of course, then we can fund SNAP, and we can also do a lot of other good things for the American people. But in the midst of a shutdown, we can't have a federal court telling the president how he has to triage the situation," Vance said on Thursday night.

"We're trying to keep as much turned on. We're trying to keep as much going as possible, the president and the entire administration are working on that, but we're not going to do it under the orders of a federal judge. We're going to do it according to what we think we have to do to comply with the law, of course, but also to actually make the government work," he said.
