Education Secretary Linda McMahon told Fox and Friends that President Donald Trump "intends" to sign an executive order to dissolve the Department of Education, but it's still unclear when.

"I don't know. I don't want to get ahead of the president," she said, adding "I think you'd have to check with the White House."

The White House pulled the expected signing on Thursday, citing concerns of blowback the order would receive, specifically if vital federal programs could no longer exist. Without giving any details, McMahon said she and Trump have spoken about the order and he is "crystal clear" on the move.

As ABC News previously reported, a draft of the order calls on McMahon to facilitate a department closure by taking all necessary steps "permitted by law," sources said.

"He certainly intends to sign the order," McMahon said. "His intent is to provide quality education through school choice to all students, and he wants to make sure that education is back at the state level where it belongs, that that our local school boards, that governors and teachers and parents are really the ones that are involved mostly in their children's education."

Trump is set to sign more executive orders at 2 p.m. ET. It's not clear what the orders will address.

Later in the afternoon, at 3:00 p.m. ET, he will participate in the White House's first-ever cryptocurrency summit -- an industry in which the president and his family have a personal stake. The summit is being chaired by the White House AI and crypto czar David Sacks. Trump will be delivering remarks.

In another clip of his Fox Business interview, President Donald Trump said he sent Iranian Supreme Leader Ayatollah Ali Khamenei a letter this week saying he hopes to negotiate a nuclear deal, while also threatening military action if a deal can't be reached.

"There are two ways Iran can be handled, militarily or you make a deal. I would prefer to make a deal," he said.

"I would rather negotiate a deal. I'm not sure that everybody agrees with me but we can make a deal that would be just as good as if you won militarily. But the time is happening now, the time is coming up. Something is going to happen one way or the other. I hope that Iran and I've written them a letter, saying I hope you're going to negotiate because if we have to go in militarily, it's going to be a terrible thing for them," Trump said, adding he sent the letter Wednesday.

Trump defended his decision to reverse the tariffs he put in place just days ago in a new clip of his interview with Fox Business, saying he thought it was "a fair thing to do" for Canada, Mexico and U.S. carmakers.

“I wanted to help Mexico and Canada to a certain extent. We are a big, big country and they do a lot of their business with us whereas in our case is much less significant we do very little with Canada by comparison. I wanted to help the American carmakers until April 2. April 2 becomes reciprocal what they charge us we charge them,” Trump said.

"I thought it would be a fair thing to do, and so I gave them a little bit of a break for this short period of time," he said.
