If your child came home from school and told you he or she got straight A's but wouldn't show you the report card and wouldn't let you talk to the teacher, wouldn't you be a little suspicious?
President Donald Trump claims he is a genius but won't show us his college transcripts.
He claims he had a medical deferment from the military draft during Vietnam but won't show us the medical records.
He claims he is a billionaire but won't show us his tax returns.
He claims "no collusion" with Russia over the 2016 election, but won't show us the full, unredacted Mueller report.
He claims "no quid pro quo" but won't show us the unredacted transcript and won't allow people serving in his administration to testify before Congress.
Believe what you want about him, but I have my suspicions.
