    In an Op-Ed on free speech and the abortion debate: “The First Amendment doctrine is clear,” said Rienzi, the lawyer who represented the plaintiff, Eleanor McCullen. “You can’t simply silence speech you don’t like. The right response is to prosecute the bad guys, to attack the people who do the actual wrong thing.”

    The Washington Times

    When he arrived in Maryland on Tuesday, Pope Francis touched down not far from the spot where some of America’s first Catholics arrived nearly 400 years ago. Those early Catholic settlers arrived with none of the fanfare that greeted the pope. But they helped establish a quintessentially American approach to religious differences — an approach President Obama has been ignoring as he litigates against the Little Sisters of the Poor and other religious ministries at the Supreme Court.

    National Review

    On Thursday, July 23, the Little Sisters of the Poor, women religious who dedicate their lives to Jesus Christ and the service of the elderly poor, went to the Supreme Court of the United States for the second time for religious-liberty protection. Last week, the Tenth Circuit ruled against them, insisting that they comply with the coercive abortion-drug, contraception, and female-sterilization mandate that the Obama administration continues to stand by. Mark L. Rienzi is the Becket Fund for Religious Liberty lawyer who is representing the Sisters (meet Sister Constance here), and a professor at the Catholic University of America’s (my alma mater) Columbus School of Law. He talks about the case.

    Catholics, Contraception and the New Health Care Law

    Rienzi discusses regulations requiring employers to include birth control in their health care plans. Catholic groups lobbied hard for the exemptions to include faith-based organizations such as Catholic universities and hospitals. The White House said no and some Catholic groups said they will not comply with the mandate.
