"They just terminated me because they thought it hurt their chances of having business with Anadarko," Oransky said.
"In essence, a fishing expedition for electronic communications between activists," Willmeng explained.
Willmeng is a well-known oil and gas activist in Lafayette, and founder of East Boulder County United.
He believes the subpoenas are an effort to try and quiet the opposition.
"It's an act of political harassment against activists," he said. "It has a very chilling effect."
The subpoena orders Willmeng and the other activists to turn over "messages exchanged via social media platforms," "email, online chat logs, letters and notes of conversation," and "all written, transcribed, taped filed and photographic materials" among others.
Willmeng said he was especially surprised to be a part of the court order because he wasn't at the original Anadarko protest.
"Although I supported everything that they were doing there in Erie that night, I wasn't even an immediate part of it," he said. "We're not going to be intimidated, we're not going to back down, we are going to protect our families," he said.
Willmeng said all six activists have hired an attorney and plan to fight the subpoenas.
