Kremlin spokesman Dmitry Peskov said earlier in the day if Trump raises the issue of Russia's alleged meddling in the United States election at talks in Helsinki, Putin will be ready to once again deny it. Reporter 2: "Why won't you come and talk to us about that?"
Trump had previously stated that he believed Vladimir Putin when he previously told him that Russian Federation had not meddled in the election.
'We don't want anybody tampering with elections, ' he said.
US intelligence agencies have alleged that Russian hackers had tried to help Trump win the White House, something Russia has flatly denied.
The US intelligence community believes that the Russian government was engaged in electoral interference during the 2016 US presidential elections. When they say they didn't meddle, they're lying.
"I don't think anybody ought to have a case of the vapors" about President Trump's rhetoric on North Atlantic Treaty Organisation and Russia, Bolton said. This week, he tweeted: 'Russia continues to say they have nothing to do with meddling in our election.' And the Pentagon is reportedly studying pulling troops out of Germany.More news: Late miss will 'haunt' Germany's Mats Hummels after shock exit
The president has called Mueller's probe a "witch hunt".
The summit could irritate U.S. allies, such as the United Kingdom, who want to isolate Putin, or countries such as Ukraine who are nervous about what they see as Trump's overly friendly attitude toward the Russian leader.
The president was speaking with Mario Bartiromo on "Sunday Morning Futures" on Fox News when she asked if he'd speak to Putin about allegations the Russians have interfered in American elections. "We'll see what Russian Federation does", Trump said.
Russia had earlier denied meddling in the U.S. election campaign and Trump called special counsel Robert Mueller's probe on the Russian interference a "political witch hunt".
"That's not the position of the United States", Bolton concluded.
Previously, sanctions had been imposed during the administration of President Barack Obama in response to Russia's annexation of Crimea and its involvement in the conflict in Ukraine.
Asked about lifting of sanctions on Russia, Mr Trump appeared to be non-committal.
