Texas will sign into law a legislation that allows private citizens to sue out-of-state providers who supply abortion pills to residents of the state.
The bill - expected to be signed by the governor on Thursday - permits residents to bring lawsuits against manufacturers or distributors of abortion medication, with successful plaintiffs entitled to at least $100,000 (£74,500) in damages.
Texas has a near-total ban on abortions, and opponents of the new law say this is a way to intimidate abortion providers outside the state.
Nearly two-thirds of the abortions in the US are via medications - a two-pill regimen using mifepristone and misoprostol, administered within the first 12 weeks.
Providers who are sued would be forced to pay the pregnant woman, the man who impregnated her or other relatives the $100,000 in damages. The women who take the medication to end a pregnancy can't be sued.
