WASHINGTON (CNN) - The head of ACORN on Tuesday sharply deplored recent videos showing some of the group's workers advising people how to set up a prostitution business.
"It made my stomach turn," Bertha Lewis, chief executive officer of ACORN, told reporters at the National Press Club in Washington. "It just made you sick."
ACORN workers who did perform their tasks properly "did not deserve to have co workers who did not live up to their standards," Lewis said.
"So yes, I terminated those employees."
At the same time, Lewis defended the community organizing group and punched back at widespread criticism, touting the group's efforts in helping poor people in the areas of housing and voting.
She backed up the group's legal action in Maryland against the makers of one of the videos. Video, shot with a hidden camera, shows conservative activists posing as a pimp and a prostitute. Lewis said that "we want to hold them accountable" for what she said was breaking the law.
Similar videos were made at other ACORN offices.
