This is so not true, mnehrling. This is not a re-authorization. It gives the Executive powers that prior did not exist.
Every single administration for at least the past 40 years (that I can cite similar orders thereof) has had similar orders- which are essential to outline the structure of government if there is a disaster.
All presidential directives can be found here:

You should be careful who you get your information from (as I see from your posts..) there are a lot of fruitloops out there who like to kneejerk react to orders like this without the slightest understanding of history.
Buh Bye...
