The first quote says “support”, and involves his run for governor. He did have their support, but not their endorsement.
The second quote says “what I did AS governor, the fact that I receieved the endorsement of the NRA”. What he did AS governor was work with the NRA on the AWB bill, which was what Russert had asked about. The NRA endorsed his work on the AWB, he worked with them to make the bill better.
Both statements are true. Some people got confused and thought that his 2nd statement was referencing his first statement, so his campaign issued a statement clearing up that misconception.
You win the spin award of the year and it is only day one. LOL
