Thompson files

From NBC's Mark Murray and Joel Seidman
Well, Fred Thompson jumped the gun on us. We and others had reported that the "Law & Order" star would file papers this Monday to establish a "testing the water" presidential committee. But according to news from the AP -- which we've confirmed -- he filed that paperwork today in Nashville, TN.

In addition, we've learned that Thompson is firmly booked to appear on The Tonight Show With Jay Leno on June 12.
