WASHINGTON — President Obama said Thursday that destroying the Islamic State alone won’t stop lone-wolf terror attacks as long as disturbed people have easy access to assault weapons. Obama renewed his call for gun control legislation after a series of emotional private meetings in Orlando with the families of victims of the worst mass shooting in American history. Law enforcement officials say Omar Mateen, a 29-year-old security guard apparently inspired by a mix of radical Islamic propaganda and anti-gay hatred, shot and killed 49 people at a gay nightclub early Sunday morning.
“Those who were killed and injured here were gunned down by a single killer with a powerful assault weapon,” Obama said. “The motives of this killer may have been different than the mass killers in Aurora, or Newtown. But the instruments of death were so similar. Now another 49 innocent people are dead. Another 53 are injured. Some are still fighting for their lives. Some will have wounds that will last a lifetime.”
Obama tried to acknowledge the complex mix of motivations and causes of the Orlando attack, but focused mostly on just one: guns.
Calling on the Senate to reconsider gun safety legislation defeated after the 2012 shooting of first graders at Sandy Hook Elementary School in Newtown, Conn., Obama challenged opponents of gun control to meet with the families of the Orlando victims. “They don’t care about politics. Neither do I. Neither does Joe,” he said, standing beside Vice President Biden.
“I truly hope that senators rise to the moment and do the right thing. We can stop some tragedies. We can save some lives. If we don’t act, we will keep seeing more massacres like this,” he said.
Obama noted the role of the so-called Islamic State, also known as ISIL, in inspiring and encouraging terror attacks. But said the last two attacks — in San Bernardino and Orlando — were conducted by “deranged individuals warped by the hateful propaganda that they had seen over the Internet.”
“It’s going to take more than just our military.” he said. “If you have lone wolf attacks like this, hatched in the minds of disturbed persons, then we’re going to have to take different kinds of steps to prevent something like this from happening.”
The president also expressed support for the gay community. “It’s a good time for all of us to reflect on how we treat each other, and to insist on respect and equality for every human being,” he said. “We have to end discrimination and violence against our brothers and sisters in the LGBT community. “We have to end discrimination and violence against our brothers and sisters who are in the LGBT community — here at home and around the world
Obama’s remarks to reporters followed private meetings with victims, police officers, doctors and staff of the Pulse nightclub where the shooting happened Sunday.
“As you might imagine, their grief is beyond description,” Obama said. “Through their pain and through their tears, they told us about the joy that their loved ones had brought to their lives.”
Obama and placed 49 white roses at a memorial for the 49 victims at a performing arts center near Orlando City Hall. “Our hearts are broken, too. We stand with you,” Obama said. “We are here for you.”
In all, Obama spent about four hours in Orlando. Landing at Orlando International Airport with Sen. Marco Rubio, R-Fla. and Rep. Corrine Brown, D-Fla., Obama disembarked Air Force One and greeted Gov. Rick Scott and Orange County Mayor Teresa Jacobs, both Republicans. Obama also accepted a T-shirt from Orlando Mayor Buddy Dyer, a Democrat.
Obama and Biden then went to the Amway Center, an arena about two miles from Pulse, where an apparently self-radicalized security guard, Omar Mateen, opened fire early Sunday morning.
