question:
The Iranian ballistic missile launch that  President Donald Trump  tweeted about Saturday apparently never happened.
On Saturday   Trump  tweeted: âIran just test-fired a Ballistic Missile capable of reaching Israel.They are also working with North Korea.Not much of an agreement we have!â
Iran just test-fired a Ballistic Missile capable of reaching Israel.They are also working with North Korea.Not much of an agreement we have! â Donald J. Trump (@realDonaldTrump) September 23  2017
 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.
answer:
Donald J. Trump


question:
CLOSE White House Spokesman  Sean Spicer  doubled down on  his  claim that President Trump's inauguration was the most watched in history.  He  also said  his  intention is to "always tell the truth " but said there may be disagreement over the facts. (Jan. 23) AP
White House counselor Kellyanne Conway claimed that âalternative factsâ were employed by  Press Secretary Sean Spicer  when he tried to make the case that âthis was the largest audience to ever witness an inauguration  period  both in person and around the globe.â Actually   Spicer  got several facts wrong.
 Spicer  then read a prepared statement later that day  further criticizing the media for âdishonesty.â
 Spicer   Jan. 21: "Secondly  photographs of the inaugural proceedings were intentionally framed in a way  in one particular tweet  to minimize the enormous support that had gathered on the National Mall. â¦ We know that from the platform where the president was sworn in  to 4th Street  it holds about 250 000 people. From 4th Street to the media tent is about another 220 000. And from the media tent to the Washington Monument  another 250 000 people. All of this space was full when the president took the oath of office. We know that 420 000 people used the D.C. Metro public transit yesterday  which actually compares to 317 000 that used it for President Obamaâs last inaugural. This was the largest audience to ever witness an inauguration â period â both in person and around the globe."
At a Jan. 23 press conference   Spicer  made an alternative argument  saying the number of people watching the inauguration on TV  online and in person had to be the largest ever.
âI have a right to say if you add up the network streaming numbers  Facebook  YouTube  all of the various live streaming that we have information on so far  I donât think thereâs any question it was the largest watched inauguration  ever â  Spicer  said.
On that point   Spicer  may be correct. While Nielsen TV ratings were higher in past years  some data suggests online viewership was up compared with 2009. But there is no comprehensive measurement available that would prove or disprove this claim.
On NBCâs Meet the Press  host Chuck Todd asked White House counselor Kellyanne Conway  â[W]hy the president asked the White House press secretary to come out in front of the podium for the first time and utter a falsehood?â Conway responded: âDonât be so overly dramatic about it  Chuck. What â Youâre saying itâs a falsehood. And theyâre giving Sean Spicer  our press secretary  gave alternative facts to that.â
PBSâ âNewsHourâ also posted a timelapse video of the crowd throughout Inauguration Day  which shows it didnât quite stretch back to the Washington Monument  as Trump and  Spicer  said. And as our fact-checking colleagues at The Washington Postpointed out  other journalists had more photographic evidence on Twitter.
Metro ridership. At the press conference   Spicer  also gave inaccurate numbers for those taking the Washington  D.C.  Metro system for Trumpâs inauguration compared with Obamaâs.
But thatâs not what Metro said  and  Spicer  acknowledged that during  his  Jan. 23 press conference.
 Spicer âs 317 000 figure was the number Metro gave for riders as of 11 a.m. on Inauguration Day 2013. The comparable number  for 11 a.m.  for Trumpâs inauguration was 193 000.
Crowd-size experts.  Spicer  was right about one thing: It appears  as  he  said  that no one has scientifically calculated estimates of the crowd size for Trumpâs inauguration. Congress has prohibited the National Park Service from making official estimates after it produced an official estimate that 460 000 turned out for the so-called âMillion Man Marchâ in 1995  prompting organizers to threaten a lawsuit.
 Spicer  argued that floor coverings over the grass on the National Mall âhighlight[ed] where people were not standing  while in years past the grass eliminated this visual.â
âI donât know how  [Spicer]  kept a straight face when he said that â Doig said.
TV and online viewership. But at the Jan. 23 press conference   Spicer  emphasized the combined audience â in person  watching on TV and watching online â was the highest in history. Asked if he was now saying that it was the largest in-person crowd for an inauguration   Spicer  said  âI am not. I am saying that it was the total largest audience witnessed in person and around the globe.â

question:
NEW YORK (Reuters) - Warren Buffett  chairman and CEO of Berkshire Hathaway Inc (BRKa.N)  said his conglomerate  which is sitting on $116 billion of cash  is âmore inclinedâ to repurchase stock than pay dividends as a means to use excess cash.
Speaking on CNBC television on Monday   Buffett  said the corporate income tax rate cut signed into law by U.S. President Donald Trump in December is a âhuge tailwindâ for U.S. companies and that it is âreally good for Berkshire.â
In his annual letter to Berkshire shareholders on Saturday   Buffett  lamented his inability to find big companies to buy and said his goal is to make âone or more huge acquisitionsâ of non-insurance businesses to bolster results at Berkshire.
 Buffett  said finding things to buy at a âsensible purchase priceâ has become a challenge and is a major reason Berkshire is awash with $116 billion of low-yielding cash and government bonds  whose average maturity was 88 days as of the end of 2017.
âI am fairly confident we will find ways to deployâ Berkshireâs excess cash   Buffett  said on CNBC. âThe best chance to deploy money is when things are going down.â
 Buffett  says  he  has confidence in Wells Fargo & Co (WFC.N) Chief Executive Tim Sloan  as  he  tried to move the third-largest U.S. bank past scandals over how it treated customers including by creating unauthorized accounts.
 Buffett  likened the situation to when  he  was installed in 1991 as chairman of Salomon Brothers Inc after a former chief executive failed to tell regulators that a trader was submitting fake bids at Treasury auctions.
âDigging your way out of it takes time â  Buffett  said. â He âs got a lot to clean up.â
 Buffett  raised red flags about ordinary investors using borrowed cash to buy stocks  or buying âon margin.â
 Buffett  said it was âcrazyâ to borrow money to buy stocks and that âit is insane to risk something you have and needâ for the sake of leveraging up on stocks.  Buffett  said investors might get a âeuphoric surgeâ if they double their money in stocks  but would not be âhappier.â
