Having been a USAA member for 25 years now. I've never seen or heard of USAA getting involved in politics or legislation at any point in those 25 years.
I take them at their word.
I'm already calling and e-mailing my congresscritters, but unfortunately my Senators are Turbin Durbin and Winnie the Burris.
Yes, yes I know. No name calling in the "Many Blood Sucking Insects" Place, but given what these two have done to this country, I think that the shoe fits.....
