Hi my name is [your name] and I'm calling from [your city]. I'd like to express my opinion to [Senator/Representative] [the senator or representative's last name] on an important issue. Have I reached the right office for that?
[Usually the answer is yes, though rarely you'll be put on hold or transferred to someone else.]
Thanks!
As you may know, the president-elect has named Stephen Bannon as chief strategist. Bannon is well-known white nationalist and anti-semite and he has no business working in the White House.
I'm calling to ask that the [senator/representative] speak publicly against Bannon's appointment and against the hatred he represents.
