FBI Director James Comey and Attorney General Loretta Lynch will decide for themselves whether they will trudge up to Capitol Hill in response to Republican requests to testify about the Hillary Clinton email investigation, White House spokesman Josh Earnest said on Wednesday.

The Obama administration has “gone to great lengths to cooperate with even the most unfair of congressional inquiries,” Earnest said in response to calls from some GOP leaders to make them explain their actions in the investigation. “That’s the principle that we have lived by.”
