Speaking on ABC’s This Week, Sen. Jon Kyl of Arizona, the GOP whip, was optimistic.

“At the end of the day, I don’t think there will be a default,” Kyl said. “We will not be the ones that put the country into default.”

Republican leaders, he added, are working with Democrats to find a solution.

At this point, Kyl said, the Senate is “proceeding” with the McConnell plan and the “House of Representatives has to make its decision about what it will do.”
