While his goal remains unaccomplished, U.S. Sen. Edward Markey boldly declared Wednesday "a great day for the internet" after the U.S. Senate voted 52-47 to adopt a Markey resolution to undo the Federal Communications Commission's repeal of Obama-era internet net neutrality rules.

"Today’s #NetNeutrality victory in the Senate would not have been possible without the fierce activism of millions of individuals and an incredible coalition of advocacy groups," Markey tweeted Wednesday.

He later added, "Celebrate today’s historic #NetNeutrality victory in the Senate. But the fight in the House starts TOMORROW."

In December, the FCC approved an order reversing its Obama-era net neutrality rules, which deemed internet service a public utility and required internet providers to treat all traffic equally. Markey's resolution, which faces an uphill battle in the House of Representatives, would rescind the FCC's action and fully restore the Open Internet Order.

"It's disappointing that Senate Democrats forced this resolution through by a narrow margin," FCC Chairman Ajit Pai said in a statement. "But ultimately, I'm confident that their effort to reinstate heavy-handed government regulation of the Internet will fail."

Since January, Markey's resolution had been one vote shy of the majority it needed for passage. All 49 senators who caucus with the Democrats had indicated their support, as had Republican Maine Sen. Susan Collins. On Wednesday, Republican Sens. John Kennedy of Louisiana and Lisa Murkowski of Alaska joined the Democrats in supporting Markey's resolution.
