Speaker John BoehnerJohn Andrew BoehnerRift widens between business groups and House GOP Juan Williams: Pelosi shows her power Debt ceiling games endanger US fiscal credibility — again MORE (R-Ohio) warned Republican House members not to to celebrate if the Supreme Court rules against the healthcare law.
"There will be no spiking of the ball," he wrote in a memo to the conference.
"Republicans are focused on the economy … We will not celebrate at a time when millions of our fellow Americans remain out of work."
The memo came after a tense morning when the Supreme Court could have issued its ruling, but did not.
The next possible day for a decision is Monday, June 25. Justices could also issue a ruling later next week.

He repeated that the House will vote to repeal any part of the law, which he referred to as "ObamaCare," left standing by the Supreme Court, and that any attempt to enact new reforms will be "step-by-step."
"Republicans will not repeat the Democrats' mistakes," he wrote. "We won't rush to pass a massive bill the American people don't support."
Not one major Republican leader in Congress has made a concrete prediction about how the court will rule, according to a review by The Hill, and Thursday's memo was no exception.
"No one knows what the Court will decide, and none of us would presume to know," Boehner wrote.
Democratic leaders sent out a memo in response to Boehner's.
"It is a sad day when Republicans continue to cheer against the health benefits Americans are already enjoying, while running out the clock on the economy and pursuing policies that are dangerous to a thriving middle class. No one, except perhaps House Republicans, actually believes they 'are focused on the economy,'" it stated.
