Three House Democrats sent a letter to Twitter CEO Elon Musk on Tuesday to express “deep concern” following reports of video evidence of protests in China being suppressed on the platform.

Reps. Raja Krishnamoorthi (Ill.), Adam Schiff (Calif.) and Jackie Speier (Calif.) sent the letter to request information about recent “malicious” activities in China and any indication if the actions were directed by the Chinese government.

The letter comes after some of the largest protests in decades have happened across the country for the past few weeks against the government’s strict “zero-COVID” policy, which tries to keep the number of COVID-19 cases to as close to zero as possible.
