ID this plane

A local radio personality posted this picture of a plane flying over Tucson this afternoon wondering what it is. He doesn't seem to be asking about the small fighter that looks like a T-38/F5 to me.

Anyone know what plane or planes these are?

Boeing uses the T-38 as a flight test chase plane.  They previously used a T-33.
