Trump Brands BLM Protesters 'Thugs' After Pittsburgh Diners Shouted At

President Donald Trump has suggested certain Black Lives Matter (BLM) activists are "anarchists, not protesters" as he criticized an incident in which diners were shouted at amid unrest in Pittsburgh.

Footage which spread online over the weekend showed a group, reported to be BLM protesters, shouting at people outside an establishment in the Pennsylvania city.

This has since prompted a backlash from the president, who wrote on Twitter: "BLM Protesters horribly harass elderly Pittsburgh diners, scaring them with loud taunts while taking their food right off their plate. These Anarchists, not protesters, are Biden voters, but he has no control and nothing to say. Disgraceful. Never seen anything like it. Thugs!"

He went on to add: "....And because of weak and pathetic Democrat leadership, this thuggery is happening in other Democrat run cities and states. Must shut them down fast. Biden and his most Liberal in Senate running mate, Kamala, won't even talk about it. They won't utter the words, LAW & ORDER!"

Trump shared footage of the incident, which is embedded below and contains strong language.

In this, one person can be heard shouting "f**k the white people that built the system," at patrons outside a restaurant while another person walked up and took a drink from a person's table.

Hi, Pennsylvania,

Here is what Joe Biden voters are doing to your peaceful, elderly population

Chants of "no justice, no peace" could be heard in the background of the clip.

Newsweek has contacted the White House, the Biden campaign and the main BLM group for comment.

Trump's comments continue the law and order narrative he has touted in the run up to November's election, despite public opinion on this matter appearing to side with Biden in surveys.

He has long blamed unrest in cities across the U.S. on Democrat lawmakers, despite his election rival Biden having also dismissed violence amid unrest nationwide.

His running mate Kamala Harris (D-CA) has also condemned violence.

Trump's comments come despite polling previously suggesting the majority of Americans disapprove of his handling of protests across the nation.

Other polling suggested Americans also anticipate violence worsening if Trump is re-elected.

It is not the first time he has criticized BLM, previously calling a street painting of the words in New York City "a symbol of hate."

Protests have spread across the country following the deaths of George Floyd and Daniel Prude, and the shooting of Jacob Blake.

In scenes of violence over Labor Day, Proud Boys rushed Black Lives Matter protesters in Salem, as they held a counter protest to a rally by the far right group.
