Sister Quincy Howard, center, a Dominican nun, protests the arrival of President Donald Trump to the Saint John Paul II National Shrine, Tuesday, June 2, 2020, in Washington. Many demonstrators present said they were dismayed when Trump staged a visit to the historic St. John's Church across from the White House and held up a Bible after authorities had cleared the area of peaceful protesters. "I'm here in protest," says Howard, "of violence, of inciting violence, of systemic racism and using religion as a shield." Protests continue over the death of George Floyd, who died after being restrained by Minneapolis police officers. (AP Photo/Jacquelyn Martin)
