You seem to imply that you have a right to see Trump's tax returns. If you want this right you should get a job at the IRS.
We do have a right to know why Hillary blamed the Benghazi 9/11 on a video. It's been four years since the attack and we still do not (officially) know the origin of that claim. Hillary's denunciation of the video is available on YouTube. You should watch with the thought in mind that we now know that the video did not trigger the attack.
