Senate Republicans planned to remain in Washington for several extra days to hold affordability-related votes that vulnerable members could promote before the November midterm elections. Instead, senators spent much of Monday answering questions about White House decisions to run air campaign-style ads with taxpayer funds and rescind about $1 billion in congressionally approved spending. The developments add to Republican concerns that the economic fallout from the Iran war could threaten their majority, while creating another distraction before lawmakers return to the campaign trail. The ads promoting President Donald Trump aired during weekend football games and other programming.
