(CNN) President Donald Trump elaborated Saturday on his call to Senate Minority Leader Chuck Schumer on Friday to discuss reviving health care legislation, saying he'd like to strike at least a "temporary deal," although he did not provide details on what such an agreement might entail.

"Well, if we could make a deal, at least on a temporary basis -- because Obamacare is exploding, it's gone, the premiums are through the roof, you see what's happening," Trump told reporters at the White House. "So if we could make a temporary deal, because ultimately we're going to have it back to the states, we're going to block-grant back to the states, but if we made a temporary deal, I think it would be a great thing for people. But it's really up to them."

"Obamacare is a disaster, the numbers are out, it's exploding like I said it would," Trump continued. "So, basically, if we could do a one-year deal or a two-year deal, as a temporary measure, you'll have block-granting ultimately to the states, which is what the Republicans want, that really is a repeal-and-replace."

Trump was referring to Republican plans to convert some open-ended federal funding for Obamacare and Medicaid into a fixed amount that would be sent to states as block grants. GOP lawmakers have said this would give states more control over the program and bring health care choices closer to patients.

Trump tweeted Saturday morning that he called Schumer on Friday to talk about reviving health care legislation.
