A photo Tuesday captured a fist-pumping President Donald Trump arriving in Pennsylvania to attend a memorial service on the anniversary of the 9/11 terror attacks, prompting outrage on social media over the president's demeanor.

The image went viral on Twitter, as people criticized Trump's expression ahead of the memorial service.

Here are some of the reactions:

Trump has frequently been criticized for his behavior in relation to tragic events, particularly the September 11 attacks.

On the day of the attacks, he bragged about having the tallest building in Manhattan after the World Trade Center collapsed, a comment for which Trump still faces backlash.

During his 2016 presidential campaign, Trump made the false claim thousands of Muslims in New Jersey were cheering about the attacks after they heard the news.

"I watched when the World Trade Center came tumbling down. And I watched in Jersey City, New Jersey, where thousands and thousands of people were cheering as that building was coming down," Trump said at the time. "Thousands of people were cheering."

On Tuesday, Trump marked the anniversary of the attacks by tweeting, "17 years since September 11th!"
