WATCH: Sean Spicer holds daily White House press briefing


Update: This event has ended.

The White House press secretary is set to address the press corps on Tuesday as President Trump approves a plan arming Kurdish militia in Syria.

Two defense officials tell NBC News that this move reinforces the idea that Syrian Democratic Force, Syrian Kurds (YPG) and the Syrian Arab Coalition each have U.S. support.

Spicer is also expected to address the testimony of Sally Yates and James Clapper on Monday. During a Senate sub-committee hearing, Yates admitted to having warned the Trump administration about Gen. Michael Flynn's potentially being susceptible to blackmail due to previous communication with Russia.
