DETROIT (AP) - A Stanford University professor is returning to the witness stand in a trial testing Michigan's ban on gay marriage.
Michael Rosenfeld says he's looked at national census data of children living with same-sex parents and finds their progress through school is the same as kids with heterosexual parents.
He'll be cross-examined Wednesday in Detroit federal court. Detroit-area nurses Jayne Rowse and April DeBoer are trying to persuade a judge to throw out Michigan's gay-marriage ban. They say it violates the U.S. Constitution's Equal Protection Clause.
The constitutional amendment was approved by voters in 2004. The state attorney general's office says Judge Bernard Friedman should respect the will of voters.
