(CNN) President Donald Trump insisted Wednesday that there are "no mixed signals at all" coming from the White House when it comes to working toward a legislative solution to provide immigration protections for young undocumented immigrants living in the US.

"Congress, I really believe, wants to take care of the situation. Even very conservative members of Congress, I've seen it firsthand. If they don't, we're going to see what we're going to do. But I can tell you I really believe Congress wants to take care of it," he told reporters on Air Force One during a flight to Bismarck, North Dakota, to rally for tax reform.

On Tuesday, Trump's Justice Department rescinded the the Deferred Action for Childhood Arrivals program , saying it amounted to constitutional overreach by the Obama administration, which implemented it. In a statement after his agencies and attorney general announced the decision, Trump urged Congress to come up with a solution.

"It is now time for Congress to act!" he said.

But Tuesday evening, Trump tweeted: "Congress now has 6 months to legalize DACA (something the Obama Administration was unable to do). If they can't, I will revisit this issue!"
