President Joe Biden highlighted his administration’s efforts to impose gun restrictions on Tuesday, just hours after his son Hunter Biden was found guilty of three firearm-related felony charges in Delaware.

Joe Biden opened his speech, held at an Everytown for Gun Safety event in Washington, D.C., by declaring that gun violence prevention has been a “passion” of his “for a long, long time” before recounting his own relationship with personal tragedy — the death of his first wife and daughter.
