problem downloading C-SPAN content

[githubber94]

Though I'm able to download some C-SPAN videos, I just ran into a problem with one of them. Following is the verbose output from a debugging run.

% youtube-dl --verbose https://www.c-span.org/video/?c4936925/president-trump-criticizes-efforts-remove-office
