The U.S. Justice Department said on Friday it would investigate the rising tide of hate crimes in America, as Asian Americans have experienced a growing number of racially motivated attacks since former President Donald Trump began referring to COVID-19 as a "China virus."

"The United States is currently facing unprecedented challenges, some of which are fueling increased bigotry and hatred," said Pamela Karlan, the principal deputy assistant attorney general for the Civil Rights Division.

She added that her office is working with the FBI, federal prosecutors and local police to "evaluate possible hate crimes," without providing further details.
