Critics are calling out President Donald Trump for marking Memorial Day with a wild all-caps rant in which he slammed the previous administration as “scum,” attacked former President Joe Biden, and railed against judges who’ve blocked parts of his agenda.

Trump on Monday wrote:

Memorial Day is typically a somber holiday intended to honor the nation’s war dead.

Trump, however, spent at least part of the day airing his grievances.

In addition to the all-caps rant on his Truth Social page, he also fired off another threat at Harvard University, gave a speech at Arlington National Cemetery in which he bragged that he has “everything” during his second term in office, and reposted a message calling Biden a “decrepit corpse.”
