Both of Hawaii’s U.S. senators took to Twitter on Tuesday to support the case for marriage equality being heard by the U.S. Supreme Court.

Sen. Mazie Hirono tweeted from outside the court, where she joined jubilant advocates marking the occasion with celebratory placards, hugs and plenty of media interviews.

“Proud to join folks from all over the country to tell the Supreme Court that #LoveCantWait,” posted Hirono, using a hashtag that trended heavily throughout the morning. “As a long time supporter of marriage equality, it’s clear that #LoveMustWin #SCOTUS.”

Schatz’s social media gave a strong indication of how he thinks the court will come down on the issue when it makes its expected ruling in June. “Today as #SCOTUS begins to hear arguments on #MarriageEquality, I’m confident it will rule that marriage equality is a constitutional right,” he said. “Committed couples, whether they are gay or straight, deserve to be treated equally under the law. … The Supreme Court has the opportunity to make history and do what is right.”

Schatz also released a similar press statement on the court proceedings that noted he had signed an amicus brief to the court in March 2013, urging justices to nullify the federal Defense of Marriage Act (DOMA).

The court subsequently gutted a significant portion of DOMA in its historic Windsor v. United States ruling, which paved the way for an astonishing series of federal court decisions legalizing same-sex marriage in 28 states and raising the overall number of marriage equality states to 37 plus the District of Columbia.
