"Whoever says we are foes is spreading fake news", Tusk, a former Polish prime minister, wrote on Twitter.
President Donald Trump headed into his first summit with Vladimir Putin on Monday determined to forge a personal bond with the Kremlin chief, saying only "stupidity" by prior administrations had brought US-Russian ties to their present low.
He again described Justice Department special counsel Robert Mueller's ongoing investigation as a "witch hunt" that has hampered US relations with Russian Federation.
"We are doing everything in our power to prevent Russian interference in 2018", he said.
"I hope it has more importance than simply for Finland, meaning I hope we'll receive a slight indication that the tensions are decreasing or at the very least that there won't be any new tensions", he stated in an interview with SVT, the public broadcaster of Sweden, on Friday. "I think the European Union is a foe, what they do to us in trade", he said.
"That's what one of the purposes of this meeting is, so the president can see eye to eye with President Putin and ask him about it", he told ABC News.
During the 2016 presidential campaign, Clinton expressed similar sentiment about the Trump-Putin relationship.
He added: "Russia is a foe in certain respects".
"Well, I might. I hadn't thought of that, but, certainly, I will be asking about it", Trump said.More news: Roku TV Wireless Speakers are both intriguing and concerning

Trump and Putin have held talks several times before. Russian Federation denies interfering in the US presidential election.
The whole world is awaiting the landmark summit between the U.S. and Russian leaders, which is scheduled for Monday on the final leg of Trump's European tour.
Schumer also urged the Senate to take up legislation to boost security for USA elections and to revive a measure passed earlier by the Judiciary Committee to protect Special Counsel Robert Mueller's investigation into Russian election interference. The two leaders will meet one-on-one with only interpretors, followed by a working lunch accompanied by advisers.
But Trump crossed a line with his comments Monday, Murphy said, by "throwing the entire intelligence community under the bus".
"I go into a meeting like that never with high expectations, but maybe some really good stuff can happen", he said.
Ahead of their meeting at Finland's Presidential Palace, both leaders made brief opening remarks to reporters.
"We'll be talking about Syria", he said.
His latest statements come days after the special counsel indicted 12 Russian intelligence agents for interference in the 2016 USA presidential election.
CBS's Jeff Glor asked Trump whether he would ask Putin to extradite those Russians to the United States. They are going to spy on us. But privately, a State Department official and a source familiar with preparations says summit planning was so rushed that the No. 2s at the major departments - like State, Defense and Treasury - did not convene specifically on this summit through the National Security Council.
