The White House has been cagey about why the president needs to be back in Washington for those discussions.
Part of the decision appears aimed at countering criticism that Obama is spending two weeks on a resort island in the midst of so many foreign and domestic crises.
Yet those crises turned the first week of Obama's vacation into a working holiday. He made on-camera statements on U.S. military action in Iraq and the clashes between police and protesters in Ferguson, Missouri. He called foreign leaders to discuss the tensions between Ukraine and Russia, as well as between Israel and Hamas.
"I think it's fair to say there are, of course, ongoing complicated situations in the world, and that's why you've seen the president stay engaged," White House spokesman Eric Schultz said.
Obama is scheduled to return to Martha's Vineyard on Tuesday and stay through next weekend.
Even though work has occupied much of Obama's first week on vacation, he still found plenty of time to golf, go to the beach with his family and go out to dinner on the island.
He also attended a birthday party for Democratic adviser Vernon Jordan's wife, where he spent time with former President Bill Clinton and Hillary Rodham Clinton.
That get-together between the former rivals-turned-partners added another complicated dynamic to Obama's vacation. Just as Obama was arriving on Martha's Vineyard, an interview with the former secretary of state was published in which she levied some of her sharpest criticism of Obama's foreign policy.
Clinton later promised she and Obama would "hug it out" when they saw each other at Jordan's party. No reporters were allowed in, so it's not clear whether there was any hugging, but the White House said the president danced to nearly every song.
