Two men were arrested and charged on Monday for allegedly using bear spray on U.S. Capitol Police officer Brian Sicknick during the insurrection at the U.S. Capitol on Jan. 6, the Washington Post reports.

Why it matters: Sicknick died from injuries he sustained while responding to the attack by pro-Trump rioters. Authorities have not determined whether the spray assault was the cause of Sicknick's death.

• The suspects arrested include Julian Elie Khater, 32, and George Pierre Tanios, 39.
• The two individuals racked up nine charges total, including assaulting a second USCP officer and a D.C. Metropolitan Police officer.

The big picture: Sicknick lied in honor at the Capitol last month and has remained a focus of investigations into what went wrong during the insurrection.

• House Speaker Nancy Pelosi said at Sicknick's funeral: "Our promise to Brian’s family is that we will never forget his sacrifice. We must be vigilant as what President Lincoln referred to as the harsh ‘artillery of time.’ "
• "We will never forget. With your permission, may we be worthy to carry Brian in our hearts. We will never forget."
