White House national security adviser John Bolton will travel to Russia this month to discuss a possible summit meeting between Presidents Donald Trump and Vladimir Putin, the White House and Kremlin announced Thursday.

“This trip will indeed happen,” Mr. Putin’s spokesman Dmitry Peskov was quoted as saying by Russia’s state media Thursday, first announcing Mr. Bolton’s planned trip.

NSC spokesman Garrett Marquis confirmed the plans in a statement, saying Mr. Bolton in a trip from June 25 to June 27 plans to visit London and Rome, then travel to Moscow to discuss the “potential” summit meeting.

Mr. Bolton will be one of the highest-ranking Trump administration officials to visit Moscow, after former Secretary of State Rex Tillerson visited last year.

The Wall Street Journal reported this month that the White House has begun early preparations for a potential Trump-Putin summit. Mr. Putin has also been lobbying European leaders to help to help set a concrete date with the White House.
