They will take concessions from Republicans for this, of course, to make it more palatable for them to defend themselves if Dems are adamant about passing DA.

Trump, I truly believe, is lying and backtracking from the promises he made Pelosi and Schumer. I strongly believe though that he would pass the budget deal with DREAM act in tote. It's not like he can amend it from the budget bill. He will not veto a government funding bill or the debt ceiling.
