Attorney General Loretta Lynch on Tuesday for an on-the-ground update on the Pulse nightclub shooting in which 49 people were killed.
Lynch, who was also due to meet with survivors, also warned that investigators may never fully know what truly motived gunman Omar Mateen to carry out the deadliest mass shooting in U.S. history.
“I can't tell you that we will ever narrow it down to one motivation,” she said.
Thousands around the world have gathered in solidarity with the LGBT community in the wake of the shooting, which in addition to the dead, injured 53 others at the popular gay nightclub.
Little new information on the federal investigation was released Tuesday as investigators continue to interview witnesses and processing the crime the scene.
The Department of Justice (DOJ) will be contributing $1 million in emergency funds to the Florida law enforcement to cover overtime expenses for police who have been working long hours since the shooting on June 12.
Lynch's visit came one day after the FBI released transcripts of the 911 calls made by Mateen from inside the nightclub. Initially, officials planned to release a redacted version of the exchange between Mateen and dispatchers, but decided to release the full transcript under pressure from lawmakers.
The transcripts confirmed that Mateen had pledged support to Abu Bakr al-Baghdadi, the leader of ISIS, during the attack, however, authorities have said there is no evidence he was directed by any foreign terrorist group. Instead, the FBI believes Mateen was self-radicalized.
“Unfortunately, the unreleased transcript that named the terrorist organizations and leaders have caused an unnecessary distraction from the hard work that the FBI and our law enforcement partners have already been doing to investigate this heinous crime,” a DOJ spokesperson said.
