John Bolton has teased his supposedly blockbuster book for months now, with quietly leaked claims that he knew of other impeachable incidents that fit the pattern of President Trump’s behavior toward Ukraine. The New York Times, which obtained an advance copy of The Room Where It Happened, reports that Bolton believed Congress should have dug into similar appeals Trump made to foreign adversaries in the explicit hopes of improving his reelection odds.

“Mr. Bolton, however, had nothing for scorn for the House Democrats who impeached Mr. Trump, saying they committed ‘impeachment malpractice’ by limiting their inquiry to the Ukraine matter and moving too quickly for their own political reasons,” the New York Times writes.
