On Tuesday President Barack Obama gave an address outlining the executive actions he's taking to combat America's gun violence problem.

He began by invoking the shooting of Rep. Gabrielle Giffords, who was seriously injured in a mass shooting in Arizona five years ago this week. Giffords was in attendance while Obama said that no one is taking anyone's guns away, just expanding background checks to make it harder for guns to end up in the hands of criminals.

"It wasn't the first time I'd had to address the nation in response to a mass shooting, nor would it be the last," Obama said and then listed other one-name mass shootings that have occurred during his presidency: Aurora, Newtown, Charleston, San Bernadino.

But it's not just mass shootings that contribute to America's gun violence problem, Obama said, it's gang violence, domestic violence, suicide, and accidents that also contribute to the annual average of 30,000 deaths by gun in America.

Obama said that despite America's polarization on the gun issue, people for the most part agree on what needs to be done: work on preventing the next mass shooting.

To that end, Obama called for expanding background checks for gun buyers. All arms sellers must obtain a license and conduct background checks or be subject to prosecution, both on- and offline. Background checks will also be expanded "to cover violent criminals who try to buy some of the most dangerous firearms by hiding behind trusts and corporations."

In order to enforce these background checks, 200 more ATF agents will be hired to work with gun sellers and more personnel will be hired to process background checks. The application process will also be updated.

Additionally, $500 million will be allocated to increase access to mental health care, and Obama called for more research into gun safety technology in the private sector.

After outlining his plans, he invoked more mass shootings of the sort that his legislation will hopefully discourage. When he mentioned the first graders killed in Newtown, a wave of emotion hit him and he began to cry a little bit.

"Every time I think about those kids it makes me mad," he said, wiping away a tear.

Obama famously cried during a speech right after the 2012 shooting in Newtown as well.
