President Donald Trump has officially met his Russian counterpart, Vladimir Putin.
The two leaders have a high-profile meeting set for 9:45 a.m. ET Friday morning, but appear to have already met more informally at the G-20 summit.
Germany, the G-20 host country, posted a behind the scenes video on its official cabinet Facebook page of various world leaders greeting each other.
Trump's more official meeting with Putin will take place amid crumbling US-Russia relations. The president currently faces multiple congressional and FBI investigations into Russia's interference in the 2016 election and whether the Trump campaign played a possible role in it.
The two presidents also took part in a G-20 "family photo" in Germany.
