(Reuters) - U.S. stock futures dropped on Friday as investors braced for President Donald Trump's response to China's national security legislation for Hong Kong, threatening to take the shine off another month of strong gains for Wall Street.
Trump is due to make an announcement later in the day and has vowed a tough U.S. response to China's move, which many fear could erode some of the U.S. economic privileges that Hong Kong enjoys.
U.S. stock indexes sold off late in Thursday's session as worries about souring relations between the world's two biggest economies and an expected executive order related to social media companies weighed on the sentiment.
While investors have kept a close eye on the rise in Sino-U.S. tensions in recent weeks, Wall Street's main indexes are set to end May with second straight month of gains on belief that the economy would rebound from the virus-led downturn.
