Washington, March 21: US President Dold Trump called his Russian counterpart Vladimir Putin to congratulate him on his re-election, leading to fresh criticism of his muted tone towards Moscow amid an ongoing probe into Russian interference in the 2016 US presidential election. In a telephonic conversation on Tuesday, Trump did not raise with Putin the “lopsided” ture of his victory, Russia’s meddling in the US presidential polls or Moscow’s role in a nerve agent attack on a former Russian spy and his daughter in the UK, the Washington Post reported.
