Regarding DHS’ potential shutdown, here’s Speaker John Boehner (R, OH):

We want to get a conference with the Senate. Now, they’ve made clear that they don’t want to go to conference. But they’re going to have a vote.

And

A spokesman for [Senator Harry (D, NV)] Reid said Sunday there will be no negotiations with the House over Homeland Security funding and immigration.

That spokesman, Adam Jentleson, added:

Senator Reid has been clear for days on the fact that there will be no conference[.]

Finally, Senator Dianne Feinstein (D, CA):

We want a clean bill. I see nothing else happening, other than a clean bill.

There you have it. The Democratic Party of No is intent on shutting down DHS in order to support President Barack Obama’s unconstitutional immigration-related “executive actions.”
