Removing gov link from page 1

I had experience with removing links from page 1 but I never did work with gov links. Usually i would just power up high da properties and after 6 months all the bad links would be gone from page 1. But this one gov link has not moved after 4 months. I'm running out of ideas. I'm driving me crazy.

Has anyone had experience removing gov links from page 1 ?

We've done fbi.gov, justice.gov and a few others. They've always been the same as other strong sites in my experience. I treat them like any other negatives. Great content on great sites, great links and you're done.
