In a recent speech, Pres Biden spoke at a lectern that had an insignia with an American eagle but the insignia did not have any words.
Here’s a close up
My guess is that he was speaking as president of The United States of America but doesn’t want to use the words on the lectern since he usually speaks at president of the UNITED STATES, which can be just the territories or the corporation.
Usually, when speaking with foreign nations, he stands in front of a flag without a gold fringe border. Whereas when he speaks to the territories, he speaks in front of a flag with the gold fringe border, because UNITED STATES declared martial law in the territories long ago.
