Under the bill, transporting a pregnant minor in or outside Idaho would be considered human trafficking.
Idaho outlaws abortions with exceptions for rape, incest, or life-threatening circumstances.
Proposed by Republican Rep. Barbara Ehardt of Idaho Falls, House Bill 98 expands the state's existing trafficking laws and would restrict alternative ways a pregnant minor might seek an abortion.
Idaho shares borders with states that have no restrictions or allows abortions up to fetal viability, including Oregon, Montana, and Wyoming.
However, no state so far has passed legislation that would ban abortions conducted outside of one's state residence.
