Donald Trump spent the weekend ahead of Memorial Day playing golf and pushing conspiracy theories on Twitter, insulting his political enemies like Joe Biden, Barack Obama, Hillary Clinton, Nancy Pelosi and Stacey Abrams and insinuating that MSNBC host Joe Scarborough is guilty of murder.His tweet storm only continued on Memorial Day before he visited the Tomb of the Unknown Soldier in Arlington, Virginia, and Fort McHenry in Baltimore, Delaware, to honour those who've lost their lives while fighting for America.
