President Obama could deliver his long-awaited endorsement in the 2016 presidential race as early as Wednesday, his chief spokesman suggested on Monday.

“Maybe he will,” White House press secretary Josh Earnest told reporters with a grin when asked at his daily briefing whether Obama would finally make it official on June 8.

Earnest also seemed to reject Bernie Sanders’ contention that his battle with frontrunner Hillary Clinton for the Democratic nomination would continue even if she meets expectations Tuesday and secures a majority of pledged delegates after primaries in California and New Jersey. She holds a lopsided edge over the Vermont senator among “superdelegates,” who will help decide the party’s nominee at its convention in Philadelphia this summer.

“We’re going to give Democratic voters the opportunity to weigh in,” Earnest said, “but certainly somebody who claims a majority of the pledged and superdelegates, you know, has a strong case to make.”

Some of President Obama’s top aides and some of his former senior advisers have repeatedly made clear that he views Clinton as his political heir. But the president has not formally jumped into the fray, mindful that one of his most important jobs in 2016 will be uniting the Democratic Party after an especially contentious primary season.

“The president intends, certainly through the fall if not earlier, to engage in this campaign, and to engage in this debate about the future of our country — and that’s an opportunity that the president relishes,” Earnest said. Obama enjoys campaigning and “he is good at it,” the spokesman added.
