John Bolton's book delayed until May because of White House review

The publication of former national security adviser John Bolton's book "The Room Where It Happened" has been delayed from March 17 until May as the White House continues to review the manuscript, CNN reports.

Why it matters: The memoir, which claims that President Trump linked Ukraine aid to investigations of his political rivals, was at the heart of Trump's impeachment inquiry — although Bolton ultimately never testified before the House or Senate. The Trump administration says that it is reviewing the book's content to ensure it does not endanger national security, though Bolton publicly worried last month that the White House may use the review process to suppress its publication.
