U.S. National Security Adviser John Bolton met with Russian President Vladimir Putin Wednesday.
The meeting comes as officials from the White House and the Kremlin have reportedly been laying the groundwork for a summit between President Donald Trump and Putin.
A spokesperson for the Russian president told reporters Wednesday's meeting would focus on "the sorrowful state of our bilateral relations."
Bolton hasn't always been supportive of U.S.-Russian relations. Just last year, before he became a Trump administration official, he said the U.S. negotiated with Russia at its own peril.
But Trump has said he'd like to improve the U.S.' relationship with Russia, which is at a low point following disagreements over issues like Syria, Ukraine and Russia's alleged interference in the 2016 U.S. presidential election.
Bolton is scheduled to hold a press conference in Moscow at 7:30 p.m. local time. Reports suggest that he could announce the date and location of a Trump-Putin summit.
