When he left the White House, Donald Trump improperly, perhaps illegally, took with him boxes upon boxes of sensitive, classified documents he was not entitled to have in his possession. As a result, the FBI raided his Florida home to retrieve these important records.
This could not have been done on a whim. The FBI would have needed high-level judicial approval for such a raid, and to get that would have had to show significant evidence that it was necessary.
Now, high-level members of the GOP are screaming for revenge: the same people who screamed loudly against the “Defund the police” movement are now screaming “Defund the FBI.”
The explanation for this is simple: To them, we are a nation of laws, except for Republicans, whom they consider to be above the law.
