Whistle-blowers are supposed to report to the American public when something bad or illegal is going on within an organization or administration. A leaker is someone who disseminates information from within an organization or administration with ill-intent.
This White House has had a disgusting amount of leaks
since Trump first took office back in 2017 and even had some before this in the 2016 transitional period. The leaks are usually out of context and often hurt the US as a whole, these are not whistleblowers they are partisan leakers who have infiltrated the President's administration with the sole intent of destroying the Trump Presidency.
