President Trump and Secretary of State Rex Tillerson are meeting with Russian Foreign Minister Sergey Lavrov at the White House today. After the meetings, Tillerson and Lavrov will head to the Arctic for a summit.

Among the topics of conversation of today’s meetings will be the ongoing conflict in Syria. On Tuesday, White House Press Secretary Sean Spicer spoke about Trump’s arming of the Kurdish People’s Protection Units, known as the YPG, which are part of the U.S.-backed Syrian Democratic Forces fighting ISIS.

Press Secretary Sean Spicer: “Yesterday, the president authorized the Department of Defense to equip Kurdish elements of the Syrian Democratic Forces as necessary to ensure a clear victory over ISIS in Raqqa, Syria. The SFD—the SDF, partnered with enabling support from U.S. and coalition forces, are the only force on the ground to successfully seize Raqqa in the near future.”

The U.S. also backed the YPG under President Obama.
