Russel Calka was one of the two people behind the 'Disclosure Activists' initiative. The other was Lisa Galarneau.
On www.disclosureactivists.org/about.html, he describes himself as follows: "Russ has been fascinated by the UFO topic since childhood and is an impassioned leader in the Disclosure movement. Previously an active member of the Disclosure Lobby, Russ has now taken the reins for the U.S.- based Disclosure effort. Russ@DisclosureActivists.org"
Thus far, the only thing he has done was organize one petition, which failed massively, and reached approx. 1% of its initial goal. Nothing of relevance happened after that.
