Copy to Clipboard Donad Trump, Ann Coulter (Getty Images) Conservative pundit and author Ann Coulter slammed President Donald Trump for hesitating to order American flags to be flown at half-staff on federal property to mourn US Capitol Police Officers Brian D. Sicknick following the siege on January 6, especially since it was reported that Sicknick was a big supporter of the POTUS. The proclamation by Trump to lower the flags at the White House and other federal buildings came days after flags at the Capitol had already been lowered. After Sicknick died Thursday from injuries he sustained during the Capitol riots, Trump had faced criticism from both sides of the political spectrum for not ordering flags to fly at half-staff. It was only after Capitol Police Officer Howard Liebengood died by suicide on Sunday that the White House released the proclamation. Flags will be flown at half-staff at the White House and all public grounds and U.S. military facilities around the world, as well as international embassies, legations and consular offices, until sunset on Wednesday, January 13.
