After a July 4 weekend celebrating independence and unity, members of Congress return to the Capitol this week with a full plate of partisan issues. Chief among their short-term priorities is highway funding, which runs out at the end of the month. No solution would mean trouble in the midst of the busy summer driving and construction season. Also likely to dominate much of the July session is a potential Iran deal. If a deal is reached by July 9, Congress will have 30 days to review it. This all comes against the backdrop of a government funding debate with a September deadline and lawmakers looking to avoid a shutdown at all costs. We take a look at priorities for Congress ahead of the August recess, and beyond.
