US President Donald Trump has admitted his son met a Russian lawyer in June 2016 "to get information on an opponent", but argues it was legal. It is his most direct statement so far on the reason for Donald Trump Jr's meeting with Kremlin-linked lawyer Natalia Veselnitskaya at Trump Tower. Special Counsel Robert Mueller is investigating US intelligence findings that Russians conspired to sway the election in Mr Trump's favour. President Trump denies any collusion. He has called the ongoing investigations in the US "the greatest political witch hunt in history". Russia has repeatedly denied claims it interfered in the November 2016 presidential elections, where Mr Trump defeated Democratic rival Hillary Clinton. SOURCE: BBC NEWS ---DECRYPTED---
