WASHINGTON (CBS NEWS) — Congressional Republicans say they will launch an investigation of Planned Parenthood as a result of an undercover video released by the Center for Medical Progress, an anti-abortion group, asserting the women’s health organization sells body parts from abortions.

The founder of the Center for Medical Progress also told CBS News his group has up to a dozen additional videos of top officials from Planned Parenthood across the country talking about the sales, which will be released in the days to come, reports CBS News correspondent Jan Crawford.
