The uninvited guests were welcomed by Issa's District Director Bill Christiansen, who listened carefully and answered questions from the demonstrators who took part in the brief sit-in.
Issa sent this statement to the demonstrators and media:
"I welcome all viewpoints and appreciate the opportunity to hear concerns from my constituents on important issues like these. Their visit today is apt considering that tomorrow we will vote on a comprehensive counter-terrorism bill which includes a measure that will keep guns out of the hands of terrorists, while also protecting law-abiding Americans' second amendment rights. In a democratic process, we need everyone to reach out and express their concerns -- today is no different."
The demonstrators also held a rally in downtown Vista, where they held signs and chanted "no more silence, end gun violence."
