BUFFALO, NY — Congress could vote on an immigration reform bill this week.

"There was pressure that reached the point where it was being put on Congress, Republican Congresspersons in the House and the Senate, and it was only a matter of time before word got back to the President that you can't do this, you've got to change this policy, " said Kevin Hardwick, political science professor and Republican commentator.

Hardwick says it's now up to Congress to clean up the mess created by the President's "zero tolerance" immigration policy that put thousand on children in federal detention facilities.             

"I don't think there's going to be comprehensive immigration reform overnight. It's been years since we've had that, I don't have a high degree of confidence that this Congress is going to let something happen. I think you're going to have to at least wait for the next Congress for that to happen at least after the midterm elections. In the short term, however, I think there are going to be increasing calls to reunite these families, to undo the damage that's been done in the last few weeks," said Hardwick.

"One thing is quite clear, we're talking about stopping separated families, but we're not talking about stopping detaining families," said Buffalo State Political Science professor Anthony Neal.

Neal says despite the President's reversal, it doesn't fix the problem.

"Essentially what you could have from this moment going forward are whole families simply in detention for an indefinite period of time. They're already trying to rescind a ruling in terms of keeping the kids in custody beyond 20 days. There trying to do away with that process so they can indefinitely detain children and  families together," said Neal.

Sen. Chuck Schumer (D) is calling on the president to appoint a czar to help reunite children separated from their families.
