An attorney for Richard L. Campbell, the man accused of punching a protester outside a Donald Trump rally in Asheville, North Carolina, last month tells Breitbart News that a new video produced by James O’Keefe’s Project Veritas showing a Democratic consultant claiming responsibility for the incident should exonerate her client.

“Mr. Campbell never assaulted anyone,” attorney Ruth Smith told Breitbart News via e-mail. “He went to a political rally as was his Constitutional right.

“As a result of Ms. Teter’s hoax, he and his wife have been tarred and feathered in the media and he has been charged as a criminal. It’s disgusting that people would do this sort of thing to innocent people, and worse that they seem to make a sport out of it.”

Campbell, 73, was accused of sucker-punching 69-year-old Shirley Teeter, who wears an oxygen tank. Teeter’s claims were picked up by national media, and a warrant was issued for his arrest by local police.

Smith told Breitbart News at the time that Teeter had “made up the whole thing.” She noted that Campbell, who has cataracts, cannot see well and was being led through the throng of protesters by his wife. She pointed to Facebook video that shows Teeter approaching Campbell from behind and apparently reaching for his shoulder. He turned around, she said, and Teeter fell down.

The Project Veritas video shows Scott Foval, a consultant for Democracy Partners, who works with the Democratic National Committee and the Hillary Clinton campaign, taking credit for Teeter’s supposed “assault.”

He describes her as a participant in a tactic called “bird-dogging,” where trained activists are sent to Trump rallies to instigate violence, either inside or outside. The goal is to create bad press for Trump and a sense of “anarchy” around him that will frighten voters.

Foval nods when asked if Democracy Partners is responsible for the incident and confirms that she was “trained,” though he adds that his group did not have direct contact with Teeter. “We didn’t know who she was ahead of time,” Foval says.

“We just had somebody who connected with her before that rally. And we knew that she was putting herself out there to draw a fire. That’s all we knew.”

Focal also explained to Project Veritas’ undercover journalist how Democracy Partners arranges for a volunteer to help activists with press coverage, to maximize the impact of each “bird-dogging” incident, wherever it occurs.

He also explained that “bird-dogging” operations can recruit activists from any demographic group, using focus groups to filter potential participants, including the elderly.
