After a successful summit last week, President Trump invited Russian President Vladimir Putin to the White House. He has subsequently put off such an invitation until next year, but that doesn't mean a second summit won't happen before then.

President Putin on Friday announced that he is inviting Trump to visit Moscow for a meeting. Putin further said he is "ready" to go to Washington for talks, but appears to want to have Moscow on the table as an alternative, since Trump appears to fear the political consequences of having Putin visit the White House before the Mueller investigation wraps up.

White House officials say that Trump is "open to visiting Moscow upon receiving a formal invitation." It's not clear when this visit would happen, but it seems likely that Putin is trying to get another formal meeting soon after the Helsinki summit.
