Story highlights Since the video's release earlier this week, conservative elected officials have slammed its contents

But allegations that Planned Parenthood sells baby body organs and tissue is unfounded, said Cecile Richards, the group's president

(CNN) Planned Parenthood's president apologized Thursday for a top official's tone in a controversial video, but she also denied the clip's allegation that her organization profits from tissue donation.

"Our top priority is the compassionate care that we provide. In the video, one of our staff members speaks in a way that does not reflect that compassion. This is unacceptable, and I personally apologize for the staff member's tone and statements," said Cecile Richards, the group's president, in a video out Thursday. "As always, if there is any aspect of our work that can be strengthened, we want to know about it, and we take swift action to address it."

Since the video's release on Breitbart earlier this week, conservative elected officials have slammed its contents and called for congressional hearings on the incident, including House Speaker John Boehner and House Majority Leader Kevin McCarthy.

"I hope that everyone in the country watches it," said Rep. Ann Wagner, R-Missouri, who called the video "the most horrifying and heartbreaking undercover video I have ever seen" during a Capitol Hill news conference on Wednesday.
