The fact that he was passing on what his medical advisors told him didn't matter - it was Trump telling them something! RESIST!
Of course, I also remember the same libs laughing at him when he said that he had been spied on by the FBI, as I remember the libs laughing at him when he said that he could rescue the economy, as i remember the libs laugning at him when he said he could win the election...etc., etc..
Basically, Trump has been right on virtually everything he says that the left laughs at and thinks is impossible. It is a character flaw of theirs
