WASHINGTON — Five lawyers will take turns at the Supreme Court lectern Tuesday for the highly anticipated and extended arguments over same-sex marriage.

Among them are the Obama administration's top lawyer at the high court, with more than two dozen arguments behind him, and two lawyers making their first appearance before the justices.

The cases come from Kentucky, Michigan, Ohio and Tennessee. Those states had their marriage bans upheld by the federal appeals court in Cincinnati.

The justices will hear 2½ hours of arguments on these two questions: whether same-sex couples have a constitutional right to marry and whether states must recognize same-sex marriages from elsewhere.
