Welcome to D.C., David Cameron. President Obama and British Prime Minister David Cameron held a joint press conference today, but the duo was met with a barrage of questions on the Benghazi embassy attack and the IRS’s targeting of conservative groups. Obama dismissed questions about Benghazi, saying, “There’s no there, there.” As for the allegations about the IRS, Obama promised to investigate. “I have no patience for it. I will not tolerate it,” he said. “You don’t want the IRS ever being perceived to be biased.”
