LIVE: Trump delivers national security address aboard USS Iowa

GOP front-runner Donald Trump delivers a major speech on national security and veterans' issues from aboard the USS Iowa, a decommissioned battleship moored in the Port of Los Angeles.

The event — dubbed “Make America’s Military Great Again” — takes place on the eve of the second GOP debate, and was organized by Veterans for a Strong America.

General admission tickets start at $100, with all proceeds going toward "helping Vets for a Strong America carry out its mission of helping our warriors on and off the battlefield.”

Members of the military both active and retired are admitted for free.
