“President Trump’s aides and confidants are growing more and more concerned about his mental state following days of erratic behavior, wild outbursts, and bizarre fixations,” Business Insider reports.

His mood changes from one minute to the next based on some headline or tweet, and the next thing you know his entire schedule gets tossed out the window because he’s losing his shit.” “They believe that his frustration is compounded by stress about the 2020 election and the economy’s recent downturn.”
