New Zealand's Prime Minister has promised changes to the country's gun laws following last week's mass shooting. FOX's Jacqui Heinrich joins us to discuss the gun debate there and how social media giants were slow to stop images of the tragedy from going viral.

Democrat media standout Beto O'Rourke announced his run for president and while there are more hints at a Joe Biden run, it's not official yet. We speak to Democrat Strategist Mary Anne Marsh about these two candidates and whether or not they pose a threat to President Trump.

Plus, commentary by FOX's Senior Judicial Analyst Judge Andrew Napolitano.
