There is no evidence that can prove the involvement of Russians in the MH17 crash.
Sergei Skripal took part in producing the Trump dossier.
The supervisor of the former GRU agent Sergei Skripal at the British intelligence office was Christopher Steele, head of the Russian division at MI6. Steele is the author of the so-called “Russian dossier” on U.S. President Donald Trump, a report that talks about the alleged link between the current White House head and the Kremlin.
According to the Daily Mail and The Telegraph, the original information linking Skripal to the Trump dossier, detailing Donald Trump's alleged links to the Kremlin, was posted on a LinkedIn page, which is no longer available and "proved to be false".
