Dozens of liberal-leaning advocacy groups are demanding that GOP leaders immediately halt their probe into Planned Parenthood, which they argue sets a "dangerous precedent" for congressional investigations.
In a scathing letter sent Monday, the groups urge Speaker Paul Ryan (R-Wis.) to disband the 10-month investigation that they claim exists solely for political purposes.
"We believe the panel's actions offend basic standards of fairness and respect for the rights of American citizens," the groups wrote in a letter provided to The Hill.
