Pro-Trump protestors breached the U.S. Capitol on Wednesday afternoon, violently clashing with law enforcement as lawmakers were gathered inside to formalize President-elect Joe Biden’s victory in November’s presidential election.

Law enforcement instructed lawmakers to retrieve masks from under their seats amid the clashes. The Capitol building was placed on lockdown, as Trump supporters marched through evacuated public spaces in the building.

After egging on protests, Trump tweeted to his supporters to “stay peaceful” as they violently clash with law enforcement and breached the Capitol building.
