Jon Huntsman, the U.S. ambassador to Russia, is helping to set up the meeting, though the planning is still in its early stages, the Journal reported.

“This has been an ongoing project of Ambassador Huntsman, stretching back months, of getting a formal meeting between Putin and Trump,” a senior administration official told the Journal.

If it comes to fruition, the summit would be the third meeting between Trump and Putin. The two leaders met on the sidelines of Group of 20 summit in Hamburg, Germany, last July and again in Vietnam during the Asia-Pacific Economic Cooperation summit in Vietnam in November.

During a phone call between the two leaders in March, Trump extended an invitation to Putin to come to Washington.

The prospective meeting would come at a point of heightened tensions between Washington and Moscow.

The U.S. intelligence community revealed in a report made public last year that Russia had sought to meddle in the 2016 presidential election to sway the race in Trump's favor.

Russia's role in the election and whether Trump's campaign colluded with Moscow is still the subject of a criminal investigation being conducted by special counsel Robert Mueller Robert (Bob) MuellerCNN's Toobin warns McCabe is in 'perilous condition' with emboldened Trump CNN anchor rips Trump over Stone while evoking Clinton-Lynch tarmac meeting The Hill's 12:30 Report: New Hampshire fallout MORE.

The U.S. has also condemned Moscow's support for the government of Syrian President Bashar Assad, as well as Russia's military intervention in eastern Ukraine.

Relations became even frostier in March, when the U.S. and dozens of other countries expelled Russian diplomats from their borders in response to the poisoning of a former Russian spy and his daughter in the United Kingdom with a military-grade nerve agent.

Russia has denied responsibility for that poisoning, and has blamed the U.S. for orchestrating a blackmail campaign against it.
