He has had the FBI, CIA, intelligence agencies from US "allies" like the UK government, coordinated with the big tech companies like Google,
going through his life with a fine tooth comb for at least 4 years, and has any information provided to the mainstream media crafted, and sensationalized to undermine anything and everything he does...
and you're worried about his ***** tax returns (that no president is required to reveal) and his medical records (does he seem unhealthy?).
