Supreme Court Chief Justice John Roberts on Tuesday temporarily blocked a congressional subpoena that seeks information on how the classified advertising website Backpage.com screens ads for possible sex trafficking.

The order came hours after Backpage CEO Carl Ferrer asked the high court to intervene, saying the case threatens the First Amendment rights of online publishers.

A federal appeals court ruled 2-1 on Friday that the website must respond to the subpoena within 10 days. Roberts said Backpage does not have to comply with the appeals court order until further action from the Supreme Court. He requested a response from the Senate Permanent Subcommittee on Investigations by Friday.

The Senate panel has tried for nearly a year to force Backpage to produce certain documents as part of its investigation into human trafficking over the Internet.

After the website refused to comply, the Senate voted 96-0 in March to hold the website in contempt. The vote allowed the Senate to pursue the documents in federal court, marking the first time in more than two decades that the Senate has enforced a subpoena in court.

A federal district judge sided with the Senate last month, rejecting arguments that the subpoena was unconstitutional, overly broad and burdensome. The U.S. Court of Appeals for the District of Columbia Circuit agreed.

A woman accused of holding her 4-year-old stepson in a scalding bath, covering his burns and not getting him medical care before he died was sentenced to at least 18 years in prison after pleading guilty to murder and other charges on Thursday.

A Warren County judge sentenced Anna Ritchie to 18 years to life in prison after she changed her plea from not guilty.

Ritchie was arrested after the March death of Austin Cooper. A detective said Ritchie told police that she put Austin's legs in extra-hot water as punishment because he didn't like baths and that she tried to hide his burns.

Her attorneys had tried unsuccessfully to have evidence from her interview with Franklin police detectives excluded from the case.

County Prosecutor David Fornshell alleged that Ritchie held Austin in extra-hot water for 20 to 25 minutes as he struggled, then put him to bed wearing pajamas and socks to cover his bleeding feet and burned skin, his arms cut where her fingernails had grasped him. His father found him dead in his crib more than 16 hours later, Fornshell said.

New York's highest court expanded the definition of parenthood Tuesday by ruling that former same-sex couples may seek visitation and custody of children even when they aren't the biological or adoptive parent.

The Court of Appeals decision resolves two cases of former unmarried same-sex couples in which the biological mothers kept the children and their ex-partners sought legal standing to see them. In one case, lower courts ruled the ex-partner had no standing. In the other, the ex-partner pays child support and was later granted visitation.

A 25-year-old definition of parenthood required a person seeking custody or visitation to have a biological or adoptive connection to the child. In its decision, the court said the standard had become "unworkable" in light of society's "increasingly varied familial relationships."

"Where a partner shows by clear and convincing evidence that the parties agreed to conceive a child and to raise the child together, the non-biological, non-adoptive partner has standing to seek visitation and custody under Domestic Relations Law," reads the opinion written by Judge Sheila Abdus-Salaam.

New York began recognizing same-sex marriages in 2011, and children born into a marriage are considered the children of both parents. But the law was far murkier when it came to same-sex couples who had a child before the law was enacted or who have foregone marriage. Same-sex partners often found it impossible to seek visitation or custody of a non-biological child they had not adopted if the relationship ended.
