Rank has its privileges, but Brent Scowcroft in shorts looked like just another potential security risk to one Secret Service agent Saturday.

The national security adviser was on his own midday jog in Houston's steamy Memorial Park when he came upon a pack of reporters waiting for President Bush to run by.The retired Air Force general and former Utahn stopped to chat, but a Secret Service agent rushed over and brusquely chided him: "Keep walking, sir. Keep moving." When the reporters burst out laughing, the Houston-based agent recognized the sweaty jogger.

"I'm just looking at shorts and T-shirts," the agent apologized with a shrug.

As the agent shooed other joggers away, Scowcroft joined his boss as the president finished his run with a pack of local joggers.
