President Joe Biden and Vice President Kamala Harris will share the stage on Tuesday in Virginia as they campaign for abortion rights, a top issue for Democrats in an election expected to feature a rematch with Donald Trump, the former Republican president.

Biden and Harris will be joined by their spouses, first lady Jill Biden and second gentleman Doug Emhoff. It’s the first time the four of them have appeared together since the campaign began, a reflection of the importance that Democrats are putting on abortion this year.

Harris was in Wisconsin in Monday to mark the 51st anniversary of Roe v. Wade, the U.S. Supreme Court decision that legalized abortion nationwide. The decision was overturned two years ago, and Trump helped pave the way by nominating three conservative justices to the court during his term. He recently said he was “proud” of his role.
