The Trump administration declared Monday that taxpayer-funded clinics must stop referring women for abortions effective immediately.

Family planning clinics that refer women for abortions will be stripped of their Title X funding, according to a measure instigated by President Donald Trump’s administration as reported by CBS News.

The Department of Health and Human Services has alerted clinics that they will be enforcing the Trump administration ban, according to CBS.

The rules now require that organizations that perform abortions and make abortion referrals will have to do so in separate buildings from those that receive Title X federal funds – a move could potentially cost Planned Parenthood “tens of millions of federal family planning dollars,” according to Politico.
