The need to borrow more money has been aggravated by several bipartisan budget agreements to raise military and nondefense domestic discretionary spending. And it could increase if the trade war further chills business investment and consumer spending, resulting in slower economic growth and fewer tax dollars flowing to the Treasury Department.

But while the nonpartisan CBO has placed the blame squarely on things like the trade war and tax cuts, Republicans—the ones who spent eight years under Obama screaming about fiscal responsibility and bankrupting our grandchildren—have an idea for how to deal with the situation that doesn’t involve taking tax cuts away from the wealthy or reeling in Tariff Man:

Conservative groups—which largely supported Mr. Trump’s tax cuts—have pushed Congress to cut future deficits by reducing benefits for federal health care and retirement programs, like Medicare and Social Security. “Something must be done soon,” the conservative advocacy group FreedomWorks said in a news release on Wednesday, “and that means taking a hard look at mandatory spending, the root cause of the United States’ fiscal woes.”

While Republicans do not expect Trump to push for cuts while campaigning for reelection, they’ve apparently encouraged him to do so should he win a second term—a proposition to which President “I’m not going to cut Social Security, I’m not going to cut Medicare” has reportedly been receptive. “We’ve got to fix that,” Senator John Thune, the number two Republican in the Senate, told the Times. “It’s going to take presidential leadership to do that, and it’s going to take courage by the Congress to make some hard votes. We can’t keep kicking the can down the road. I hope in a second term, he is interested,” Thune said of Trump. “With his leadership, I think we could start dealing with that crisis. And it is a crisis.” Republicans, said Senator John Barrasso, who seems to regularly chat with the president, have “brought it up with President Trump, who has talked about it being a second-term project.”
