A group of more than 100 Republican lawmakers is asking for an investigation into the amount of federal funding that has been awarded to health centers that also provide abortion, including Planned Parenthood.

Sen. Marsha Blackburn (R-Tenn.), as well as House Pro-Life Caucus Co-Chair Rep. Chris Smith (R-N.J.), led a letter to the Government Accountability Office on Friday, asking for a report on the funding sent to the groups over the past three years.
