It was just one year ago that the city of Orlando, Florida was rocked by the worse mass shooting in American history. After Donald Trump decided to acknowledge anniversary of the tragedy on Twitter, social media users were quick to fire back.

Trump on Orlando

It was June 12, 2016 when 26-year-old Omar Mateen opened fire inside the Pulse nightclub in Orlando. The target were members of the LGBT community as Mateen carried out his act of terror resulting in the deaths of 49 innocent people, while leaving many others injured. In the aftermath of the shooting, Mateen was revealed to be an Islamic terrorist, inspired by extreme religious groups in the Middle East like the Islamic State (ISIS), while being raised in a strict Muslim family in the United States.

The shooting took place during the heat of the 2016 presidential election [VIDEO], which Donald Trump used to continue his push for a ban on Muslim immigration in the United States. Fast forward a year later and the city is still reeling from the aftermath, while coming together in an emotional show of unity. As the one-year anniversary of the shooting arrived, the city and nation looked back at the innocent lives lost at the hands of a terrorist. On his Twitter account on Monday, Trump decided to give his thoughts.

Taking to his personal Twitter feed, Donald Trump acknowledged the Orlando shooting at the Pulse nightclub.

"We will NEVER FORGET the victims who lost their lives one year ago today in the horrific #PulseNightClub shooting," Trump tweeted, while using the hashtag, "#OrlandoUnitedDay." Trump's tweet comes as his so-called "Muslim ban" continues to remain in the spotlight, while taking place just two weeks after a similar Islamic terrorist attack occurred in London.

Twitter reacts

Not long after Donald Trump sent out his tweet about the Pulse nightclub shooting, critics hit back hard in response. "You *JUST* passed an executive order allowing discrimination against gay people by businesses under the guise of religious freedom!" Jules Suzdaltsev tweeted out.

"We will also never forget how you made the shooting about you one year ago today," Upworthy editor Adam Mordecai wrote on his Twitter account.

"this ALL CAPS tweet does not absolve u from throwing the entire LGBTQ comm. under the bus after your election. Liar!" Dennis Herring added.

"If you want to remember the victims of the #PulseNightclub shooting, you should protect LGBT rights," Edward Hardy wrote on his Twitter feed. "Honor the LGBTQ community who want safe spaces to exist by protecting trans kids and protect the equal rights of the LGBTQ community," comedian Kristina Wong wrote. The negative backlash to the president continued as it was clear that his stance on the Pulse nightclub shooting would not go without push back.
