Speaking without TOTUS is apparently too grueling for the president.
He looks like Dean Martin after a few too many Martoonies! I refuse to watch him or even listen to him so thanks for the posted picture.
TOTUS is his crutch. He never has been able to talk very coherently without TOTUS. Partly or greatly, that is because he lacks a sufficient knowledge of the topic/situation/crisis/event. That is why he seems to ramble — he is under the guise that words coming out of his mouth result in a response to the question.
Additionally, one who typically is telling a lie tends to flood their response with a lot of words which may or may not be relevant. A liar thinks he/she must explain in greater detail. The more words it takes for them to answer a simple question, more you can bet they are constructing a deception or a lie.
