US shutdown and travel?

Have seen anything in the news, so assume this is ok - but...
Does anyone have evidence or information that would indicate that immigration and/or air traffic control services etc could be interrupted due to the US government shutdown?
Travelling tomorrow, so am keeping an eye on this situation...
Thanks for any info/thoughts.
