PHILADELPHIA (CBS) — Donald Trump takes his campaign to Center City this morning. At 11 a.m. he delivers a policy speech on the military and national security.

It is Trump’s second visit to the city in less than a week.

Police and Secret Service on South Broad Street. Media satellite trucks lined up as well in front of the Union League. Here, Trump talks to an invitation-only crowd. Foreign policy, national security, leading the military, the hot topics in the days leading up to the anniversary of the 9/11 attacks.

Trump, at a stop in Virginia yesterday, revealed a list of 88 retired military leaders who support him.

“These are our fighters. These are fighting generals.”

Hillary Clinton, on the stump in Florida said, “I will give our military everything they need when they’re serving overseas.”

Trump back in town today. It was only last Friday when he was here, speaking to African American leaders in North Philadelphia.
