The big questions surrounding the Nunes memo

Rep. Devin Nunes, the author of the memo.

President Trump's Chief of Staff, Gen. John Kelly, said Wednesday that the White House plans to authorize the release of a controversial House Intelligence Committee memo "pretty quick." But the FBI shared a public statement expressing "grave concerns" about the memo's accuracy, and its impending release.

Why it matters: Republicans are anxious for the memo to become public, and have hinted that its release could be explosive. But Democrats and the FBI claim it's a highly flawed document that will just fuel the polarization surrounding the Russia probe.
