They are discussing the Trump Administration cabinet, which are appointed positions in the executive branch of government.  Murkowski and Sullivan are in the legislative branch and have elected positions.  Mickey Mouse could be elected President and they still would be the US Senators for Alaska, that is why they aren't mentioned.  It would be nice if you understood the three branches of government.  What you fail to understand is that it will now be easier for Murkowski to open up ANWR and other policies she has discussed, but connecting the dots must be hard.
