The Transportation Security Administration (TSA) has acknowledged an increase in the number of its employees who stopped work during the partial judgment of the Government. Agency employees are expected to work without pay during the closure because their work is considered essential.

The TSA said in a declaration On Friday, visits that began during the holiday period increased. The agency did not specify the number of calls from its employees who were called, but she said that internal calls had "minimal impact because 51,739 employees supported the process filtering ".

According to the release, waiting times "could be affected", but so far "will remain in TSA standards".

"TSA is monitoring the situation closely," the statement said. "The effectiveness of security will not be compromised."

The Department of Homeland Security (DHS) and President Trump on Saturday dismissed the suggestion that absences were a "disease" with significant consequences for air travel in the United States. White House officials and congressional aides were in talks Saturday to end the closure, which came in its 15th day. Negotiations are stalled on Trump's $ 5.6 billion request for a wall on the US-Mexico border.

Michael Bilello, spokesperson for TSA tweeted 5.5% of the TSA's workforce at the Dallas / Fort Worth International Airport called Friday, against 3.5% on a normal day. He stated that waiting times "could be affected", but that all passengers would be controlled normally.

Hydrick Thomas, President of the National Union of TSA Employees, said CNN up to 170 employees of the TSA at John F. Kennedy Airport in New York have called each day this week. Airport officials said there was no control time at Chicago's JFK, O'Hare and Midway airports, or at Miami International Airport.

"This will certainly affect the flying public we have vowed to protect," Thomas told CNN.

Union officials did not return requests for comments.
