President Obama said he will not “campaign for, vote for or support any candidate, even in my own party who does not support common-sense gun reform,” in a New York Times op-ed released Thursday.

Though Obama has made clear he will continue advocating for gun control throughout the remainder of his second term, the president admitted defeat saying it’s clear gun reform will not happen in this Congress or his presidency. Still, he wrote, the whole of the U.S. has a collective responsibility to confront the crisis.

“All of us need to demand leaders brave enough to stand up to the gun lobby’s lies. All of us need to stand up and protect our fellow citizens,” he writes. “All of us need to demand that governors, mayors and our representatives in Congress do their part.”

Obama’s op-ed was published shortly before the President took the stage at a town hall event on guns in America hosted by CNN, and two days after he announced a series of executive actions on gun control. The two leading Democratic candidates for President, Hillary Clinton and Bernie Sanders, expressed support for the executive actions, making it unlikely that Obama’s ultimatum would affect a member of Obama’s party.

In the editorial, Obama calls gun violence a “national crisis” that requires a “national response” and listed a number of examples of what he called “common-sense” reforms, such allowing consumer safety requirements for guns, conducting more research on the public health impact of gun violence, and making it easier to bring lawsuits against manufacturers.”

The President also reiterated that all Americans have a role to play in reducing gun deaths, which he said claim more than 30,000 American lives every year.
