3:32 p.m. ET: CBS has fired company lawyer, Hayley Geftman-Gold, for posting on Facebook that she had no sympathy for those injured or killed in the Las Vegas shooting because "country music fans often are Republican."

The comments were eventually deleted, but screenshots circulated of the originals, which said, "If they wouldn't do anything when children were murdered I have no hope that Repugs will ever do the right thing. I'm actually not even sympathetic bc country music fans often are Republican gun toters."

Geftman-Gold was responding to a conversation regarding the Sandy Hook elementary school shooting and media coverage surrounding such mass shootings. Several individuals called for her to be fired from CBS for the comments.

"This individual, who was with us for approximately one year, violated the standards of our company and is no longer an employee of CBS. Her views as expressed on social media are deeply unacceptable to all of us at CBS. Our hearts go out to the victims in Las Vegas and their families," a CBS spokeswoman told Fox News.

3:11 p.m. ET: Police have not publicly identified a motive for Las Vegas gunman Stephen Paddock, but officials said he had a history of gambling and once filed a lawsuit against a Las Vegas casino, which was later dismissed. He rented two rooms at the Mandalay Bay hotel and brought 19 guns and hundreds of rounds of ammunition into the hotel before the attack.

Darrel Stephens, executive director of the Major City Chiefs Association, told Newsweek that Paddock "likely had those [guns] concealed in some way, more than likely in luggage." Rifles are "easy to disassemble," he said, and the huge hotel constantly sees people coming and going with luggage.

2:48 p.m. ET: The GoFundMe page to raise money for the victims of the Las Vegas shooting has raised more than $820,000 in five hours.

Vice President Mike Pence and his wife, Karen Pence, also joined in the moment of silence.

2:24 p.m. ET: Russian President Vladimir Putin conveyed sympathy and support to Americans in a statement on the Las Vegas shooting. Putin "wished a speedy recovery" to those injured in the attack, which is estimated at 515 people injured and 58 killed. "The crime that took the lives of dozens of civilians is shocking in its cruelty," Putin said.

The Russian leader also expressed condolences after the Pulse nightclub shooting in Orlando, Florida, when former President Barack Obama was in office.

2:13 p.m. ET: White House spokeswoman Sarah Sanders said it is "premature" to call the Las Vegas shooting that killed 58 "domestic terrorism" and "there is a time and a place for political debate, but now is time to unite as a country."

At a press conference Monday, Sanders said, "Today is a day for consoling survivors." She reaffirmed President Trump's support for the Second Amendment but declined to say if he might support any gun restrictions.

1:45 p.m. ET: One hour and 12 minutes elapsed between the first call to police and breach of Stephen Paddock's hotel room, reported NBC. President Trump has thanked first responders and local police for quickly arriving on the scene.

1:40 p.m. ET: Las Vegas gunman Stephen Paddock, 64, had rented two hotel rooms, one facing north and one facing east, at the Mandalay Bay Hotel before the mass shooting. He checked into the hotel on Thursday, Sept. 28 with at least 19 weapons and hundreds of rounds of ammunition, though it is unclear how they were transported.

Clark County Commission Chair Steve Sisolak confirmed that Stephen Paddock had visited the hotel two other times, and was using his roommate's slot machine card at the hotel and casino. She was in the Philippines at the time of the shooting, reported the Nevada Independent.

After breaking the window of his room on the 32nd floor, likely with a hammer, police said, Paddock fired hundreds of shots, which witnesses said sounded like machine-gun fire. The smoke from his shots set off a smoke alarm and alerted police to his location.

The attack, which injured 515 and killed 58, is the deadliest mass shooting in U.S. history.

"Obviously in this situation where we have this many patients needing care, we need all the medical personnel that are available," said Amy Shogren, a spokeswoman for the Nevada Hospital Association.

12:33 p.m. ET: Representative Seth Moulton, a Democrat from Massachusetts, said he will not participate in a moment of silence on the floor of the House of Representatives to honor those killed and injured in the Las Vegas shooting.

Moulton said on Twitter that he believes a moment of silence "becomes an excuse for inaction." He followed with a secondary Tweet that said, "Now is not a moment for silence; it's a time for action."

Moulton also reposted a photo of himself serving in Iraq. He posted it after the Orlando shooting at Pulse nightclub with the caption, "I know assault rifles. I carried one in Iraq. They have no place on America's streets." He has criticized lawmakers who promise other mass shootings will be the last time without taking legislative action, saying he is "praying Congress will have the courage to do more than stand in silence to commemorate them."

11:48 a.m. ET: House Majority Whip Steve Scalise, who recently returned to work after being injured in a shooting at a GOP-baseball practice in June, said in a statement, "I agree with the president that this was an act of pure evil. I pay for the victims of this murderous attack, and our whole nation grieves with their loved ones. We also thank the first responders and fellow citizens who did all they could to help those in harm's way. In this tragic moment, I encourage people across America to stand together in solidarity, and to support the Las Vegas community and all of those affected, especially by giving blood and encouraging others to do the same."

A U.S. official, unauthorized to speak publicly and speaking on condition of anonymity, told Newsweek, "There is no indication that there is any link whatsoever. They claim a lot of things."

ISIS regularly claims attacks in the West even if it has not directed them, instead suggesting that it played a role in inspiring them.

9:38 a.m. ET: Brett Kenyon, a 26-year-old who works at the Cosmopolitan of Las Vegas, a hotel on the Strip, said he was waiting on a table of eight men when he was told about the shooting. The Las Vegas hotel went into lockdown around 10:45 p.m. and no one could enter or leave the building, but they were able to see people from the restaurant windows.

"We could see people on the Strip, just people running and looking scared," Kenyon told Newsweek. "There was lots of confusion as to if there were multiple shooters."

Kenyon said watched the police and SWAT teams arrive through the restaurant window. After two hours of being under lockdown, and waiting in a "panic" for news about what happened, the hotels were released. Kenyon will return to work Monday night.

9:09 a.m. ET: The suspected shooter killed himself before police gained entry to his room in the Mandalay Bay Hotel, according to Las Vegas Sheriff Joe Lombardo.

In his latest press briefing, Lombardo said that Paddock had been using the ID of Marilou Danley, a woman that police earlier named as a person of interest in the investigation. The sheriff said that police had located Danley outside the United States and that she was not thought to have been involved in the attack.

Lombardo also said that Paddock had checked into the hotel on Thursday and that police had not yet been able to establish a motive for the attack.

Asked why the attack had not been described as domestic terrorism, Lombardo said: "We have to establish what his motivation is first. There are motivating factors associated with terrorism other than a distraught person just intending to cause mass casualty. Before we label with that it will be a matter of process."

Paddock told The Daily Mail that there was "absolutely no indication he could do something like this" and added that he had no political or religious affiliation. "He was just a guy. Something happened, he snapped or something," Paddock told The Daily Mail.

Paddock has given a statement to police and said he would comment further later.

8:02 a.m. ET: The White House said it is monitoring the Las Vegas shooting closely after a gunman fired hundreds of rounds into a country music festival, killing dozens and forcing thousands to flee the area.

Stephen Paddock, the 64-year-old suspected shooter, died of a gunshot wound at the scene, Las Vegas Metropolitan Police Undersheriff Kevin McMahill told CNN. McMahill would not confirm whether the gunshot was self-inflicted. There were at least eight firearms found in Paddock's hotel room in Mandalay Bay Hotel and Casino.

White House officials and those close to President Trump began responding to the shooting Monday morning. Ivanka Trump said, "America woke up this morning to the horrific news of a devastating mass shooting in Las Vegas. Our collective hearts are breaking for the victims and their families." Donald Trump Jr. tweeted, "Our prayers and deepest condolences are with all those affected by the evil perpetrated in #lasvegas."

The Las Vegas Metropolitan Police Department said "Our condolences go out to the families who lost loved ones tonight. Thoughts and prayers are with all of those affected by this tragedy."

7:50 a.m. ET: A gunman opened fire Sunday night at an outdoor music festival in Las Vegas, Nevada, killing at least 50 people and injuring 200, marking the deadliest shooting in recent U.S. history.

Police named the suspected shooter as 64-year-old Stephen Paddock, who is confirmed dead. The attacker opened fire at the Route 91 Harvest Festival from the 32nd floor of the Mandalay Bay Hotel and Casino at around 10:30 p.m. local time, Las Vegas Sheriff Joe Lombardo said.

Several rifles were found in his hotel room, and Lombardo said the FBI will be involved in the case.

Eyewitness Quinn Mell-Cobb, 24, told Newsweek that the gunshots sounded like they were coming from "everywhere" and initially sounded like "firecrackers." The slow realization that they were gunshots resulted in mass panic and shrieks from the crowd as the gunfire continued. University Medical Center in Las Vegas reported that 104 patients have been admitted with 12 in critical condition.

President Donald Trump was briefed Monday morning on the attack and tweeted, "My warmest condolences and sympathies to the victims and families of the terrible Las Vegas shooting. God bless you!"
