The pro-life groups are taking aim at abortion providers under an initiative called Defund Planned Parenthood, which targets federal Medicaid funding for the nation's main abortion provider.
“This event begins an intensive round of outreach to the GOP, calling on them to take advantage of this unique moment to defund the abortion industry,” Students for Life, the national pro-life group organizing the event, said in a statement.
Rachel Rebouche, dean of Temple University's Beasley School of Law in Philadelphia, said the Defund Planned Parenthood movement has been building for 10 years but has gained momentum as the pro-life movement has been emboldened by Trump’s presidential victory and by his fellow Republicans winning control of Congress in November.
The Supreme Court announced it would hear a case involving South Carolina's attempt to strip Medicaid funding for Planned Parenthood. Experts say the lawsuit could prompt similar efforts in conservative states across the country to chip away at the organization's funding.
Almost 100 conservative members of Congress signed an amicus brief urging the Supreme Court to side with South Carolina. The state already bans abortion after six weeks of pregnancy.
In February, a panel of judges in the 5th Circuit Court of Appeals reversed a lower court ruling that attempted to force Planned Parenthood to repay millions of dollars of Medicaid funding in Texas and Louisiana.
Lawmakers in at least three states — Missouri, Ohio and South Carolina — have introduced bills this year aiming to create tax breaks for pro-life centers.
