A controversial abortion bill was signed into law in Georgia on Tuesday that will make it significantly harder for women seeking abortions. Under the bill signed by Gov. Brian Kemp, abortions are prohibited if a fetal heartbeat is detected in the womb.

The previous law allowed abortions up to the 20th week of a woman’s pregnancy. By making the mandate a fetal heartbeat, it’s possible a woman could be blocked from undergoing an abortion as soon as six weeks pregnant, which is the earliest a heartbeat can be detected.

"The bill is very simple but also very powerful: a declaration that all life has value, that all life matters, and that all life is worthy of protection," Kemp said at the Capitol.

Kemp acknowledged that the bill can expect a legal challenge.

"But our job is to do what is right, not what is easy. We are called to be strong and courageous, and we will not back down. We will always continue to fight for life," he said.

The law has been met with protest, with dozens showing up outside the Georgia Capitol building. There have been concerns that such laws could mean Roe vs. Wade is overturned by a Supreme Court that now includes Judge Brett Kavanaugh. 

Women’s rights groups are already planning legal challenges.

"Today's women can only thrive in a state that protects their most basic rights -- the right to choose when and whether to start a family. Georgia can't afford to go backward on women's health and rights," Andrea Young, the executive director of Georgia’s American Civil Liberties Union chapter, said in a statement.
