US National Security Advisor John Bolton said on Friday that the United States has invited Russian President Vladimir Putin to Washington.
It was not immediately clear if Putin had accepted the invitation.
Putin and Trump have met several times on the sidelines of multilateral gatherings, but had only one bilateral summit, in the Finnish capital in July. After that encounter, Trump was accused by opponents, and even some members of his own Republican Party, of failing to stand up to the Russian leader.
The topic of Putin visiting the United States is a highly-charged one, because US intelligence agencies allege that Russia interfered in the 2016 presidential election to help Trump win. Russian denies any election meddling. Trump has said it is in US interests to establish a solid working relationship with Putin.
Trump and Putin also plan to hold a bilateral meeting on the sidelines of events in Paris on November 11 to commemorate the centenary of the end of World War One. Bolton, who was speaking at a news conference on a visit to ex-Soviet Georgia, said their Paris meeting would be brief.
