President Donald Trump branded Democrats "hypocrites" over calls for an investigation into his administration's contacts with Russia, posting a photograph on the internet of one of the opposition party's leaders sharing doughnuts and coffee with Vladimir Putin.
It came after half a dozen Trump officials and advisers were revealed to have met Sergey Kislyak, the Russian ambassador to Washington, in the six months before the president took office.
Mr Trump responded by posting the picture on Twitter showing Chuck Schumer, the Democratic leader in the US Senate, smiling alongside Mr Putin during his trip to New York in 2003.
The president said: "We should start an immediate investigation into Senator Schumer and his ties to Russia and Putin. A total hypocrite!"
