House Democrats are launching a billboard campaign targeting Republicans in competitive districts over in vitro fertilization, the latest sign that reproductive care will be central to their efforts to retake the lower chamber in November.

The Democratic Congressional Campaign Committee has announced a five-figure campaign focused on six House GOP lawmakers and two former members for their support of the Life at Conception Act at one time or another. The DCCC and national Democrats have slammed the “extreme bill” in the past, and criticisms over its lack of IVF protections resurged after the Alabama Supreme Court ruled frozen embryos were children, threatening the IVF process and women who underwent such procedures.
