President Joe Biden is urging members of Congress to ban assault weapons, an effort he also led in 1994 with the passage of the Federal Assault Weapons Ban. Can he do it again?

Biden made his push for an assault weapons ban during his State of the Union address on Tuesday. The 1994 law led to a significant reduction in gun deaths, Biden said, and those rates increased after the ban expired.

Tony Montalto lost his daughter Gina in the 2018 mass shooting at Marjory Stoneman Douglas High School. Now, he leads the group Stand With Parkland, which works to make schools safer and reduce gun violence.

Montalto said on Greater Boston that the president has been trying "a multitude of things," and was encouraged by recent bipartisan support for gun safety measures. Those efforts include legislation passed this summer aimed at incentivizing states to pass red-flag laws that would petition courts to remove weapons from people deemed as a threat.

Montalto said he believes Biden is trying to bring people together from both sides of the aisle to solve the problem of gun violence, which is the best approach.
