Iowa Governor Signs Nation's Strictest Abortion Ban As Legal Challenges Mount

Iowa governor signed a 6-week "heartbeat" abortion ban, the strictest in the U.S., but it faces immediate legal challenges.
The law bans most abortions once cardiac activity is detected, usually around 6 weeks, with limited exceptions.
Reproductive rights groups argue the ban is unconstitutional under Iowa's constitution and quickly sued to block it.
Iowa joins over a dozen other GOP-led states in passing strict abortion limits after the fall of Roe v. Wade.
Republican presidential hopefuls are split on whether to support 6-week or 15-week bans as the national abortion debate continues.
