1. Start the call by asking if they're cosponsoring of the USA Freedom Act.
2a. If they are not, use the script, it makes sense.
2b. If they are, thank them for their support of this bill. You can also let them know how important these surveillance issues are to you and the extent to which your representative's actions on these matters will affect your behavior at the polls and in donations.
Just a heads up to those planning to call (please do!). I felt kind of silly finding out that the first senator on my list was already a cosponsor after reading through the script, and wanted to save others the minor embarrassment. It should feel good to call your representatives and express your support for such important issues!
That aside, this is a really great campaign. Thank you so much to everyone who put it together and made it happen!!
