2018 Winter Olympics: Mike Pence tweets '#FAKENEWS' on report about skater Adam Rippon
At about the same time as Pence took to Twitter  a White House official was explaining to reporters traveling with the vice president to South Korea that  Pence 's team did contact the U.S. Olympic Committee. But the vice president's office was offering— not requesting — a meeting with Rippon and wanted to give the skater as much space as possible. The official declined to be identified.
Columnist Christine Brennan reported on Wednesday that  Pence  had become so concerned about criticism he faced from Rippon  an openly gay athlete  that his staff reached out to the USOC to set up a conversation between the two.
Headed to the Olympics to cheer on #TeamUSA. One reporter trying to distort 18 yr old nonstory to sow seeds of division. We won’t let that happen! #FAKENEWS. Our athletes are the best in the world and we are for ALL of them! #TEAMUSA — Vice President Mike Pence (@VP) February 8  2018
.@Adaripp I want you to know we are FOR YOU. Don’t let fake news distract you. I am proud of you and ALL OF OUR GREAT athletes and my only hope for you and all of #TeamUSA is to bring home the gold. Go get ‘em! — Vice President Mike Pence (@VP) February 8  2018
“ You mean Mike Pence  the same Mike Pence that funded gay conversion therapy ? I’m not buying  it  ” Rippon responded.
Around the same time that  Pence  sent out his two tweets over the reports about his spat with Rippon  a White House official confirmed that the vice president's chief of staff Nick Ayers called U.S. Olympic Committee CEO Scott Blackmun after Rippon had initially criticized  Pence  last month.
Rippon’s criticism of  Pence  was over language on a campaign website that some LGBT activists say shows that as a congressman the vice president had supported gay conversion therapy.
Ayers told Blackmun that the criticism of  Pence  was untrue and that he never supported gay conversion therapy  the White House official told reporters. When the issue surfaced during the 2016 presidential campaign   Pence 's then press secretary  Marc Lotter  also denied that  Pence  supported the policy.
Ayers offered to have someone from the vice president's team explain to Rippon the confusion over  Pence 's stance. Ayers also said that  Pence  would meet with Rippon or speak with him over the phone if he preferred  the White House official said.

Two attorneys representing key Donald Trump associates say they consider it possible that  special counsel Robert Mueller  could end up indicting the president for obstruction of justice  Politico is reporting.
Neither attorney claimed to have inside information about  Mueller 's plans and based their comments on their understanding of the law  according to Politico.
But the website noted many legal experts maintain  Mueller  lacks the standing to bring charges against Trump.
Still  one of the lawyers  who represents a senior Trump official  said  Mueller  could try to indict the president even if the move brings challenges from Trump's attorneys.
"It's entirely possible that  Mueller  may go that route on the theory that  as an open question  it should be for the courts to decide " the attorney said. "Even if the indictment is dismissed  it puts maximum pressure on Congress to treat this with the independence and intellectual honesty that it will never  ever get."
And one legal expert maintained  Mueller  will never indict the president.
" Mueller  will not indict Trump for obstruction of justice or for any crime. Period. Full stop. End of story. Speculations to the contrary are just fantasy.
