Senate Republicans met with President Obama for more than 90 minutes on Friday, as lawmakers search for a breakthrough agreement that could end the government shutdown and raise the debt ceiling. Like House Republicans the night before, the GOP senators departed the White House without speaking to reporters. Sen. Chuck Grassley (R-Iowa) tweeted shortly after the meeting that it was a "very good discussion." "Nothing obvious decided, but hope," he tweeted. "I'm surprised there may be progress."
