BOSTON (Reuters) -A federal judge is standing by her decision to block the implementation of a provision in U.S. President Donald Trump's recently passed tax and spending bill that would prevent Planned Parenthood health centers from receiving Medicaid funding.

Under the new spending bill, the nation’s largest abortion provider would have to stop offering abortion in some states or lose millions in Medicaid funding for basic health care.

Defunding Planned Parenthood is really an attempt to take away access to abortion in states where it is legal,” said one leader of the women’s health care organization.
