The March for Marriage in Washington, D.C., will be held on Saturday, June 25, the one-year anniversary of the Supreme Court ruling that redefined marriage.

The Obergefell v. Hodges ruling blatantly ignored the U.S. Constitution and wrongly imposed the will of five justices on all 50 states. Brian Brown, president of the National Organization for Marriage, is helping organize the rally.

“We will be marching this year to protest the unprecedented and egregiously incorrect ruling of the narrow majority in Obergefell,” he said, “as well as to advocate defense in law for the rights of people of faith to abide by the consciences and the mandates of their religion when it comes to recognizing or participating in the solemnization of same-sex ‘marriages.’”

He added that they will also speak out about the administration’s efforts to open up public school girls restrooms and locker rooms to boys.

Marriage supporters will rally in front of the Capitol, then march to the steps of the Supreme Court. You can learn more about the event and sign up at MarriageMarch.org.
