Atlanta mayor says she's concerned about Super Bowl travel impacts during shutdown

Atlanta Mayor Keisha Lance Bottoms told CNN she is concerned about the impacts of the shutdown on people traveling in and out of Hartsfield-Jackson Atlanta International Airport during Super Bowl LIII.

Atlanta will host the Super Bowl on Feb. 3.

“We’re concerned. It’s frustrating, it’s concerning. We are hosting one of the biggest, most-watched events in the world in just a few weeks and there are real concerns about will our airport be up and functioning in a way that we need it to be,” Bottoms said in an interview Thursday.

Bottoms told CNN that the city even looked into paying some Transportation Security Administration employees through the city's airport fund but were told that wasn’t possible.

“That’s a question that I asked at the beginning of the shutdown, was that something we could do through our funds associated the airport? And what we’ve been told is that we can’t, essentially. That it’s just not that simple for us to pay them. It is something we would be willing to do through our airport funds … Thus far, we’ve been told that it’s not feasible,” Bottoms said.

Trump cancels US delegation's trip to Davos due to the shutdown

President Trump has canceled next week's trip to Davos, Switzerland, for the entire US delegation due to the shutdown, White House press secretary Sarah Sanders announced Thursday.

The delegation was headed to the World Economic Forum in Davos, which is Jan. 22 to 25.

Here's what Sanders said in a statement:

“Out of consideration for the 800,000 great American workers not receiving pay and to ensure his team can assist as needed, President Trump has canceled his Delegation’s trip to the World Economic Forum in Davos, Switzerland.”

Trump canceled his appearance at the forum last week because of the ongoing government shutdown. Instead, Treasury secretary Steven Mnuchin was expected to lead the delegation.

Sen. Lisa Murkowski, a Republican from Alaska, said she is “glum” over the state of affairs with the shutdown.

Asked about her mood during the shutdown, she said, “Glum…. I’ve been discouraged."

"Many of the efforts that a good coalition of the willing have been trying to get advanced, seem to be pulled back by those that don’t want us to get out of the mess that we’re in. And I have a difficult time understanding that," Murkowski added.

Murkowski said the tit-for-tat between President Trump and House Speaker Nancy Pelosi is “wearing on me as a lawmaker."

She went on to say that she doesn't think any lawmaker should be leaving DC during the shutdown. 

Murkowski's scheduled trips to London and Norway were canceled five days ago, she said, because they couldn’t get support for the State Department due to the shutdown. It was not canceled by the administration, she said.

Democratic congressman on letter: Trump has "acted like he's in the fifth grade"

Democratic Rep. Adam Schiff criticized the actions of President Trump and accused the White House of hypocrisy with administration officials traveling to Davos.

Schiff went on to say that Trump has "acted like he's in the fifth grade."

He also said the President irresponsibly revealed a trip to a war zone. (Pelosi had been scheduled to use military aircraft for her trip to Afghanistan.)

The speaker’s office, Schiff said, spoke with the Defense Department, which was caught off guard by the President's actions.

He said the House would continue its oversight of the administration but would not say if the trip was canceled.

Separately, a Pelosi aide said the trip was supposed to be five days — not seven — as the White House claimed.

Trump has been watching the coverage of his letter to Pelosi and is "pleased"

President Trump has been watching the coverage of his letter to Speaker of the House Nancy Pelosi this afternoon and is "pleased" with the results, a White House official said.

Some background: Trump sent a letter Pelosi today informing her that he was canceling the military aircraft she would have used in an upcoming overseas trip because of the shutdown.

Pelosi was scheduled to leave for her trip this afternoon, two White House officials told CNN.

Trump's actions come one day after Pelosi asked the President to find a new date for his State of the Union address due to the ongoing shutdown.

Sen. John Cornyn, a member of Republican leadership, said the shutdown fight between President Trump and House Speaker Nancy Pelosi had "too much childishness."

Asked about the mood toward the shutdown, Cornyn told reporters it was "foul."

"Too much childishness. Not enough seriousness. People are getting hurt," he said.

Asked if Trump should have canceled the military aircraft intended for Pelosi's overseas trip, he said, "It's like tit-for-tat. I thought what she did was petty, vindictive, and this certainly doesn't elevate the debate."

State Department staff ordered to return to work

The State Department is ordering its staff back to work next week, pledging that it will find the money to pay them despite the partial government shutdown.

In an "urgent message" issued today, the 27th day of the shutdown, Deputy Under Secretary for Management Bill Todd told staff that "as a national security agency, it is imperative that the Department of State carries out its mission. We are best positioned to do so with fully staffed embassies, consulates, and domestic offices."

"As a result, all State Department direct-hire employees and State Department locally employed staff are expected to report to work on their first work day in Pay Period 2," he wrote.

They'll start work next week: Todd noted that for most employees, that will be January 22, while for others posted in countries where the work week begins on Sunday, that will be January 20.
