 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 Trumpâs 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 âdeclaration of warâ â violated the companyâs terms of service.
