The chairman of the Senate Judiciary Committee said his panel is reviewing “serious allegations” in a report that a former anti-abortion leader knew in advance the outcome of a 2014 Supreme Court case involving health care coverage of contraception.

The report Saturday in The New York Times followed the stunning leak earlier this year of a draft opinion in the case in which the high court overturned Roe v. Wade, ending constitutional protections for abortion. That decision was written by Justice Samuel Alito, who is also the author of the majority opinion in the 2014 case at the center of the new report.

In the Times story, Rev. Rob Schenck said he learned the outcome of the Burwell v. Hobby Lobby Stores case weeks before the decision was made public. In a 5-4 decision, Alito wrote that some companies with religious objections can avoid the contraceptives requirement in President Barack Obama’s health care legislation.

Schenck, who previously headed the group Faith and Action, has said in other recent stories in Politico and Rolling Stone that he was part of a concerted effort to forge social and ministry relationships with conservative justices.

In the Times story, Schenck said the information about the Hobby Lobby decision came from Gail Wright, a donor to his organization who was part of the outreach effort to the justices and who had dined with Alito and his wife. Wright herself denied obtaining or sharing any information in an interview with the Times.

The New York Times also published a letter Schenck said he wrote Chief Justice John Roberts in July alerting him to the alleged breach years ago. Schenck wrote that he thought the information might be relevant as part of a probe into the leak of the abortion decision.
