"Appreciate the congrats for being right on radical Islamic terrorism"

On June 12, 2016, the day of the Pulse Nightclub shooting, President Donald Trump apparently copied and pasted an unsourced tweet claiming that an Orlando shooter who killed 49 people in an LGBTQ nightclub shouted "Allahu Akbar!" as he committed the murders.

CNN's Brian Stelter noted in June of 2016 that the tweet was taken from former White House aide Sebastian Gorka's Twitter account. 

Trump's tweets on the day of the shooting focused largely on Islamic terrorism. "Appreciate the congrats for being right on radical Islamic terrorism," Trump wrote in one tweet, which earned him backlash from commenters on social media.

In another tweet, Trump called on President Barack Obama to "finally mention the words radical Islamic terrorism."

Some conservatives and Trump himself have long taken the Obama and Bush administrations to task for their perceived failure to acknowledge the link between terrorism and "radical Islam." 

Trump appeared to reference his proposed "travel ban" in another tweet from the day of the shooting. 

Trump signed a controversial executive order in January of 2017 that prohibited residents of some Muslim-majority countries from traveling to the United States.
