Demonstrators Sue Trump Administration Over Crowd-Clearing Tactics

The incident aimed to allow President Trump to take photos at a nearby church. The administration's actions faced criticism from military officials, including Jim Mattis, who accused Trump of dividing the public. Despite Trump's denial of tear gas use, the US Park Police admitted to using a pepper compound. The incident resulted in injuries to protesters, with police justifying their actions as necessary to control violence.
