WASHINGTON (AP) - President Barack Obama decried the deadliest mass shooting in American history on Sunday as an "act of terror" and an "act of hate" targeting a place of "solidarity and empowerment" for gays and lesbians. He urged Americans to decide whether this is the kind of "country we want to be."
Speaking hours after the shooting at a nightclub in Orlando, Obama said the FBI would investigate the shooting as terrorism but that the alleged shooter's motivations were unclear. He said the U.S. "must spare no effort" to determine whether the suspect, identified by authorities as Omar Mateen, had any ties to extremist groups.
Obama said this was "an especially heartbreaking day" for the lesbian, gay, bisexual and transgender community, and a sobering reminder that an attack on any American is an attack on all, regardless of their race, religion, ethnicity or sexual orientation.
"The shooter targeted a night club where people came together to be with friends to dance and to sing -- to live," Obama said. "The place where they were attacked is more than a night club. It was a place of solidarity and empowerment, where people have come together to raise awareness, to speak their minds and to advocate for their civil rights."
For Obama, the hastily arranged remarks were the latest in what's become a tragically familiar routine. Since he took office in 2009, Obama has appeared before cameras more than a dozen times following mass shootings and issued written statements after many others. The massacres have brought him to places like Newtown, Connecticut; Tucson, Arizona; and Charleston, South Carolina, to offer condolences and implore the nation to finally get serious about stemming gun violence.
After a gunman in Newtown killed 20 first graders and six adults in 2012, Obama dedicated much of the start of his second term to pushing legislation to expand background checks, ban certain assault-style weapons and cap the size of ammunition clips. That measure collapsed in the Senate, and since then, the political makeup of Congress have made new gun laws appear out of reach. Still, Obama has sought to take incremental steps using his own authority to tighten rules for obtaining a gun.
Obama spoke from the James S. Brady Press Briefing Room, named after the former press secretary who was shot and permanently disabled in an assassination attempt on President Ronald Reagan.
He also signed a proclamation on Sunday ordering flags to be flown at half-staff until sunset on Thursday in honor of the victims.
Vice President Joe Biden canceled a planned trip Sunday to Miami to hold a fundraiser for Rep. Debbie Wasserman Schultz, D-Fla. Biden's office said he would remain at his family home in Delaware while receiving updates about the shooting before returning to Washington in the evening.
Pennsylvania Gov. Tom Wolf ordered U.S. and state flags at the Capitol complex, commonwealth facilities and public buildings in the state lowered to half-staff in honor of the victims.
The governor said he and first lady Frances Wolf were sending their thoughts and prayers to the victims, their families and the Orlando community for what he called "the tragic and senseless terror attack and hate crime."
The shooting brought Pittsburgh's largest gay pride celebration to a brief halt. Hundreds taking part in Sunday's noontime PrideFest parade in downtown Pittsburgh paused for 50 seconds -- one second for every victim -- in honor of the victims.
New Jersey officials say they're not planning any extra security measures in the state following the mass shooting, but they’re reminding residents to remain vigilant and report any suspicious activity to authorities.
State police say New Jersey homeland security officials have not detected any credible threats in the wake of Sunday's shooting in Orlando. But they say authorities continue to closely monitor the situation.
Law enforcement authorities in the state's major cities and at the Jersey Shore -- home to many gay clubs -- said they had no immediate plans to beef up security or impose new policies.
