One thing I am curious to know is what made Donald Trump bleed two weeks ago. His bleeding hand is a footnote on a footnote on a footnote of history as, in the foreground, the vital machinery of government continues to rust from non-use. The facts of how and why he incurred a minor hand injury are likely not important enough that they should be wondered about weeks after the fact for even one second by any but the person with the absolute most time on his or her hands, which, unfortunately for me, is me.

For everyone else: On Jan. 10, the president traveled to Texas, where he was seen wearing a blood-soaked adhesive bandage on his right hand, as captured in this image on Sean Hannity’s Instagram account.

When the president stopped to speak with reporters outside the White House that morning before departing for Texas, he already had a clean bandage on his right hand. Because blood was visible during his appearance at Anzalduas Dam (scheduled for 3:30 p.m. E.S.T.), we may infer that an initial wound was somehow reopened in the intervening six hours.
