The whistleblower complaint, annotated – CNN

One of the definitions of “urgent concern” in US law is: “A serious or flagrant problem, abuse, violation of law or executive order, or deficiency relating to the funding, administration, or operation of an intelligence activity within the responsibility and authority of the Director of National Intelligence involving classified information, but does not include differences of opinions concerning public policy matters.”

This complaint, along with the related transcript of Trump’s Ukraine call released by the White House, has already led to calls for Trump’s impeachment. Remember, the Constitution says a President should be impeached not for breaking US law, but rather for committing treason, bribery or “high crimes and misdemeanors.” It’s Congress’s job to determine what those are, in what are known as articles of impeachment.
