During a 2016 U.S. presidential debate, then-candidate Donald Trump made a statement that seemed brash at the time: If he were elected and got the chance to nominate justices to the U.S. Supreme Court, the Roe v. Wade ruling that legalized abortion would be overturned.

By this time next year, with the court having tilted further to the right thanks to Trump's three appointments to the nation's highest court, his prediction could come true.

The court's decision on Wednesday night to allow Texas' six-week abortion ban to go into effect in apparent contravention of the 1973 Roe decision suggests the court is closer than ever to overturning a ruling U.S. conservatives have long reviled.
