In a press-conference today, President Obama insisted that the national-security leaks did not come from the White House. He said that he has “zero tolerance” for these kinds of leaks, and he suggested that his administration is looking to find the source of the leaks: “We will conduct thorough investigations, as we have in the past.”
He also said the idea that his administration purposefully leaked national-security information is “offensive.”
