(WASHINGTON, D.C.) — As protests against police brutality grip America following the shooting of Jacob Blake, who was shot in the back seven times by police, several demonstrations have become targeted by gun violence.

Most recently, one protestor was killed on Saturday in Portland, Oregon, where responding officers found the victim with a bullet wound to the chest.  The unidentified victim was pronounced dead at the scene.  The suspect remains at large.

In response to the shooting death in Portland and last week’s deadly violence in Kenosha, where an armed 17-year-old shot and killed two protestors, Democratic presidential nominee Joe Biden says he blames President Donald Trump for the increasing violence and civil unrest.

Biden claims the president is “fanning the flames of hate and division in our society.”  In addition, the former vice president says he holds President Trump accountable for not working across the aisle to help solve the issue.

Following the shooting death in Portland, President Trump attacked the city’s Democratic mayor on Twitter, calling Mayor Ted Wheeler “a fool” and “incompetent” before saying “Bring in the National Guard!”

“It does not matter if you find the political views of your opponents abhorrent, any loss of life is a tragedy,” said Biden.  “He may believe tweeting about law and order makes him strong — but his failure to call on his supporters to stop seeking conflict shows just how weak he is.”
