 Trump  has been criticized a number of times for jumping to conclusions and commenting on Twitter before breaking news reports have been confirmed.
As of Monday night   he  had not deleted the erroneous tweet.
Separately  Twitter Inc. TWTR  -2.30% on Monday explained that it would not block Trumpâs more incendiary tweets because they are newsworthy. Some had complained to Twitter that  his  threats toward North Korean leader Kim Jong Un â which North Korea said Monday it took as a âdeclaration of warâ â violated the companyâs terms of service.

Example Input: LAS VEGAS â Charlene and her boyfriend  were asleep in  their  room at the Mandalay Bay Resort and Casino when  at 3 a.m.  there was a sudden banging on the door. Dazed   they  thought it must be someone in another room. But the pounding continued.
When  they  finally answered the door  a SWAT team barged into the room.
" They  were going room to room  " Charlene  who declined to provide her last name   told BuzzFeed News Tuesday afternoon. " They  searched the room  the closet.  They  looked all around  and then  they  were gone." The entire ordeal Monday morning lasted only a few minutes. When it ended  Charlene  turned on the TV and learned that Stephen Paddock had opened fire from the broken windows of another suite  raining bullets down on a concert and killing at least 58 people in the deadliest shooting in modern US history. The attack has prompted an outpouring of support and mourning  but at the hotel Paddock used as his perch  its turned the once lively casino on the Las Vegas Strip into a virtual ghost town.
A spokesperson for MGM Resorts International  which owns Mandalay Bay  said that business at the hotel was "not slowing down " and that "itâs still too early to gauge near term impacts." The spokesperson added that the company is providing counseling to hotel employees and guests  and said it was "standard practice" for companies to forbid their employees to speak to the media. Still  the vacant silence was unmissable at Mandalay Bay. Kelly Powers  a self-described Vegas regular who arrived at the hotel from Houston on Monday night  said the employees she had interacted with seemed to be suffering. "I think they're traumatized " she said. "I think they're wondering why this happened  why it happened here."  Charlene  â the woman whose room was stormed by SWAT officers â and Powers were both among a handful of people passing the time Tuesday afternoon playing the slots. They had their run of the place  but  Charlene  said that as empty as the casino was  it was actually an improvement over a day earlier. "It was eerie "  she  said. "It was empty all day Monday."  Charlene   who is visiting from Canada  said that after the shooting guests were placed on lockdown in their rooms and did not receive information from the hotel about what was going on. When some tried to descend the elevators  they were told by police to return to their rooms. "We couldn't go anywhere and we couldn't do anything  we had no direction "  Charlene  said  adding they had to remain in their room until around noon Monday. When they finally were allowed to leave their room and enter the casino there were no employees in sight. "Nothing was open  there was  no staff" Charlene  recalled. "It was kind of in shambles." Despite the chaos  hotel patrons remained mostly optimistic Tuesday. Powers praised the staff "for trying to do their jobs" and  Charlene  said  she  doesn't fault the resort for what happened Sunday night. "I'm not going to blame them "  Charlene  said. "I would come back."
