From Politico:

"They're working on something dealing with border security. I'm not
telling anyone what to do other than tell them to do it as quickly as
you can," Reid said. "This may not be one of our normal weekends where
we shoot out of town."

Corker said on Monday that the group of senators working on a
compromise on border security that could appeal to both Democrats on
Republicans is getting close, but wouldn't tip his hand.

"There are a number of folks who are working together to try to
attempt to get to that place that answer the border security issue but
also does it in the way that's objective, so there's not a worry about
the goalposts being moved down the road," Corker told reporters. "I
think we're getting close. But again there's a number of conversations
underway and it continues to be slightly fluid. I just have a sense that
there's a good chance."

I know some of the pro-immigration community thinks that it's only important to get 60 votes in the Senate, but I believe that getting a sizable portion of Republicans to vote for the bill would send a powerful message to the House and would mean a better bill in the end. So I think the efforts to find a compromise on border security are important.
