You didn't get the joke Roosevelt was making.
Every time there is a mass shooting, GOP politicians say, "thoughts and prayers" instead of backing the left wing position on guns (nationwide ban on AR 15s until there is another mass shooting, then more gun control, then the 2nd amendment being overthrown, then the US losing the 1st amendment because the 2nd protects the 1st).
Roosevelt is using that same strategy for when Trump gets attacked.
