Now that the US Supreme Court has overturned Roe v. Wade, roughly half the states have legislation on the books restricting abortion.

And 13 of them had "trigger laws" to ban abortion once the 1973 ruling was struck down. Residents of those states seeking abortions must now travel across state lines to get an abortion — and Missouri wants to sue those who do.

What's more, it'll be a long drive: an average of 125 miles, compared to just 25 when Roe was still the law of the land, Ian Bremmer explains on GZERO World.
