Releasing classified documents for political purposes, is bad.
Releasing classified documents pertaining to an ongoing investigation, is bad.
Exactice, you can file complaints with a variety of sources if you think something bad is going on. The gold standard is the Inspector General, who already investigated this and released a detailed report, citing the appearance of bias, and the resulting lack of evidence to support that such bias impacted any work decisions AND that no decisions were made in a vacuum/secret by any one person...that dozens of agents/managers all saw each action, and thus, the idea that there was some conspiracy whatsoever, has been debunked.
If the IG found evidence of something beyond policy/ethics violations, they would refer it for criminal investigation.
That's the process.
What Trump/House Republicans do, is political, and sets a terrible precedent.
Exactly. These agents ARE NOT ON TRIAL FOR CRIMINAL CHARGES. And thus, we have no business seeing their personal, or work related discussions, unless there is some compelling reason. And there is not.
