Republicans are working to hammer out a last-minute deal on border security funding before leaving town for their August recess.
Meanwhile, on the other side of the Capitol on Friday, South Carolina Republican Sen. Lindsey Graham pleaded with his Democratic colleagues to take up the House proposal if passed by the body.
"If they can pass a solution to this problem, I'm urging the majority leader of the Senate to bring us back in," Graham said. "We shouldn't be gone for five weeks with something this important left unresolved."
Finding a resolution will be tough. The opposing funding plans supported by Republicans and Democrats are separated by nearly two billion dollars. Republicans are also working to pass adjoining legislation to defund elements of a 2012 executive order allowing young immigrants to stay in the United States.
